Summary.
San Francisco-based guitarist Henry Kaiser (1952) adopted Derek Bailey's approach to creative atonal improvisation and Captain Beefheart's approach to post-psychedelic timbric and rhythmic mayhem on Ice Death (october 1977), featuring both solos and collaborations with improvisers such as guitarist Eugene Chadbourne and alto saxophonist John Oswald, the duets of Protocol (december 1978), with the Japanese trumpeter Toshinori Kondo and the Italian percussionist Andrea Centazzo, the chaotic guitar duets with Fred Frith of With Friends Like These (july 1979), that was also his first experiment in using the studio as an instrument, and finally the solo album Outside Pleasure (august 1979). The double-LP album Aloha (september 1981) contained two lengthy solo showcases for his extended technique The Shadow Line, a vast catalog of abominable blues, jazz, rock and Indian mistakes, and the studio-processed Aloha Gamera (a remix ante-litteram). Kaiser successfully wed creative improvisation and ethnic music on Invite The Spirit (august 1983), for a trio with Korean zither and percussion (Charles Noyes).
Instead the 27-minute It's A Wonderful Life, off It's A Wonderful Life (september 1984), began to display his twisted genius for composition, freely adapting elements of bluegrass, blues, rock, Indian and Japanese stringed instruments. The hypnotic scales, the fractured melodies and the intricate tonal zigzagging framed by neurotic tempos were closer in spirit to an acid-rock jam or to a melodic fantasia than to Derek Bailey's blasts of noise.
Other notable pieces of bizarre improvisation were the live duet with Bill Frisell, Last Of The Few (november 1985), off Marrying For Money; the live duet with guitarist Jim O'Rourke, A Long Life Is A Slow Death, off Tomorrow Knows Where You Live (march 1991); the 25-minute solo The Five Heavenly Truths, off The Five Heavenly Truths (august 1990).


Full bio.
(Translated from my original Italian text by ChatGPT and Piero Scaruffi)

Henry Kaiser (1952), a prolific and eclectic guitarist from Oakland, California, started out in the wake of Derek Bailey with albums such as Ice Death (October 1977), a collection of seventeen Dadaist duets pairing guitar with saxophones, trombones, and cellos. Each piece is a miniature of entirely random sonic emissions in which humor prevails over rationality. It is an art of carefully calibrated dissonance, exemplified by Blue Dolphin, featuring John Oswald's chirping alto sax and Laurel Spring's hysterical vocal solfeggio, and by Wind Crystal, the album's most austere and rarefied piece, built almost entirely around guitar harmonics and mishaps, with Eugene Chadbourne on second guitar. Improvised (Music Gallery, 1978) and Moose And Salmon (February 1979 - Music Gallery, 1979) are collaborations with Oswald.

While Protocol indulges excessively in sonic effects, the live album Outside Pleasure puts Kaiser's repertoire of cacophonous tricks to work in delirious, clownish suites such as Outside Pleasure (featuring some of the most psychotic pizzicatos and crescendos ever recorded on guitar), The Stormy Present (with a chilling succession of psychedelic glissandos), and The Farmer In Heaven (echoing, however faintly, Japanese dance theater), all of them harmonic massacres haunted by missed notes and deliberate detunings.

These transitional works paved the way for Aloha, a double album that represents the culmination of this phase. The Shadow Line is Kaiser's definitive solo statement, encompassing an immense range of influences, from Hendrix-like glissandos to psychedelic distortion, from piano clusters to Cagean indeterminacy, with an electronic interlude worthy of a ghost story. The horror suite Aloha Gamera, on the other hand, was electronically processed in the studio, blending Kaiser's trademark guitar mishaps with every imaginable buzz, drone, and overdub. Yet the performance is so frenzied that, at its loudest and most chaotic moments, one seems to hear echoes of flamenco footwork and even imitations of the harpsichord.

Outside Aloha Pleasure (Dexter's Cigar, 1996) combines Outside Pleasure and Aloha.

The cassette Mah Jong Hell (Mystery Tape Laboratory, 1983) collected solo home demos with old drum machines.

With the suite It's A Wonderful Life (from the work of the same name), Kaiser's compositional technique began to display an unmistakable centrifugal pull toward the most disparate musical idioms, including bluegrass, blues, rock, Indian, and Japanese music.

With It's A Wonderful Life, Kaiser's compositional technique began to show a centrifugal drift toward a wide variety of musical idioms, both popular and classical.
What sets apart Kaiser's improvisations is that they don't seem to belong to any of the established traditions. There is little or no jazz in It's A Wonderful Life, despite the free-form format. There are, on the other hand, subtle references to the rock, bluegrass and blues traditions, and not so subtle tributes to Indian and Japanese classical music. The hypnotic scales, the fractured melodies and the intricate tonal zigzagging are framed by neurotic tempos, giving the performance a very modern, urban feeling. In fact, the overall effect is closer to an aicd-rock jam or to a melodic fantasia a` la Mike Oldfield than to Derek Bailey's guitar improvisations. The delirious (almost heavy-metal) solo of Let's Drink adds Indian drumming and funky syncopation. The Book Of Gold, instead, is a concerto for guitar noises, an austere exploration of timbres.

The albums from the first phase of Kaiser's career helped redefine the concept of chamber music in a broader sense. Even in these early works, Kaiser's avant-garde jazz is never excessively intellectual or abstract, always retaining a human element, often in the form of provocative humor. Kaiser expanded Derek Bailey's vocabulary of creative music by embracing contamination from every kind of electronic device and every form of musical gesture. As a result, he came to resemble Eugene Chadbourne more than his English mentor, eventually crossing paths with progressive rock. For example, Who Needs Enemies (October 1983), recorded in collaboration with Fred Frith, is a showcase of eccentric duets and assorted noises. His musical upbringing, after all, was that of an average Californian teenager who had grown up listening to Captain Beefheart's Magic Band and the Grateful Dead's acid jams, and whose musical philosophy reflected the spirit of the alternative radio stations of the hippie era, which freely broadcast non-commercial music while effortlessly mixing the most diverse genres.

Eclectic and chaotic, imaginative and playful, Kaiser's musical language eventually absorbed elements from virtually every culture, all enriched by his virtuosic cacophony. Invite The Spirit, inspired by Korean ceremonial music and recorded as a trio with Noyes and Korean harpist Sang Won Park, is one of his masterpieces, featuring chamber pieces in which the most improbable detunings blend naturally with the shamanic and Confucian atmospheres of sinawi.

Drawing ever closer to the world of rock, Kaiser recorded Marrying For Money (November 1985), later reissued as Re-Marrying For Money (SST, 1989), a completely improvised album performed by a hard-driving rock power trio that echoes Massacre. It displays a dazzling assortment of deliberate wrong notes (Set Up), grotesque minimalism (Big Clock, Java Jack), violent dissonance (Too Late For Tears, Tapping The Source), and magnificent Beefheart-style blues (Pigs And Battleship, Hairy Eyeball), culminating in the extended post-psychedelic delirium of Last Of The Few, a duet with Bill Frisell. With this album, Kaiser arrived at a mature way of applying his extended guitar techniques to the free improvisation of rock.

Kaiser's rock and funk souls rule on Devil In The Drain (february 1987 - SST, 1987). Sugagaki for Conlon sounds like Frank Zappa (both the verbose guitar solos and the band-like synclavier arrangements) mixed with some Weather Report and some Herbie Hancock. Dark Memory #4 is a three-part work: a dissonant keyboard study, a watercolor of atmospheric guitar tones, and a frantic Mahavishnu Orchestra-like fugue. The haunting Roadside Picnic evolves from a subdued piano sonata to a polyrhythmic industrial nightmare. The mood runs the gamut from the comic intermezzo King of the Wild Frontier to the Irish square-dance cum Japanese court ballet of If This Goes On, via the dreamy gamelan concerto of Free to Choose. The only reference to his past life as a free improviser is the intricate, quasi-raga out-of-tune guitar solo Lost Horizon, one of his best ever.

These works were followed by Those Who Know History Are Doomed To Repeat It, on which Kaiser reinterprets the Grateful Dead's Dark Star and several Captain Beefheart compositions in his own idiosyncratic style, and by Crazy-Backwards Alphabet (December 1986), recorded with a rock quartet that included John French. The album alternates white blues in the vein of John Mayall (Get To You), abstract and cacophonous instrumentals (Dropped D's, We Are In Control?), and once again revives the lopsided exuberance of the Magic Band (Lobster On The Rock).

This marked the beginning of Kaiser's era of collaborations, both in rock—most notably Live, Love, Larf & Loaf (March 1987), with Richard Thompson, John French, and Fred Frith—and in jazz, with Popular Science (May 1989), a collection of surreal sketches performed as duets with Russian keyboardist Sergey Kuryokhin. The latter is a festival of eccentricity conceived in a thoroughly postmodern spirit: Out Taco Sauce, Sales Pitch, Electricity Vs Foods, and Barking Dogs Vs Minimalists rank among the funniest and most successful comic inventions of Kaiser's career. Unfortunately, the quartet failed to recapture that spirit on the mediocre Invisible Means (March 1990 - Windham Hill, 1990).

Kaiser is a spontaneous and playful musician, eager to embrace any kind of musical experiment, though not particularly gifted as a composer. His greatest strength lies in solo performance. His finest achievements remain the solemn fantasies built around deliberately "wrong" notes in Aloha Gamera, It's A Wonderful Life, and Last Of The Few.

Heart's Desire (october 1989 - Reckless, 1990) documents a live performance by a rock band fronted by Kaiser that included industrial guitarist Bruce Anderson and Grateful Dead's keyboardist Tom Constanten, with songs ranging from garage rave-ups to languid blues-rock, an eclectic choice of covers (from Stockhausen to Neil Young via the Grateful Dead's Dark Star). A similar idea yielded Siamese Stepbrothers (Cuneiform, 1995). Hope You Like Our New Direction (Reckless, 1991) is, instead, another display of his eclectic background.

Thankfully, Kaiser returned to his free-form noise guitar roots with Tomorrow Knows Where You Live (march 1991 - Victo, 1991), duets with 22-year old Jim O'Rourke and solos of each of the two (best is O'Rourke's droning Just as A Wall Of Quiet Flowing Stands Near), Acoustics (august 1993 - Victo, 1993), a quartet with O'Rourke, Oswald and violinist Mari Kimura, and the 25-minute solo-guitar title-track of The Five Heavenly Truths (FOT, 1992).

Seven lengthy jams span the range from rocking dissonance (guKTen LIMPo) to agonizing post-blues (The Enumeration), and from thundering boogie (Disinterested Bystander) to abstract noisescape (Construction #14) via the chaos of The Celestial Squid that is both clownish and romantic. This is the perfect setting for Kaiser the jazz improviser, who too often has preferred to take the low road of solo improvisation instead of the high road of group improvisation. In reality, he excels when he is surrounded by equally creative and unorthodox souls. If nothing else, having to deal with other players bends his egocentric brainy guitar science to truly engaging and spontaneous artistic expression. Less indulgent than Megasonic Chapel and better played than Nearly Extinct or You Can't Get There From Here, this is probably the best Kaiser album of this new prolific stage.
