His solo debut came at the end of the 1970s with the album Fiddlesticks (December 1978). This na ve work contains in embryonic form his distinctive conception of jazz chamber music (particularly the lengthy Megatones for string quintet), although its intent is primarily playful. Anger immediately stands out for a style that recalls the stylistic revolutions of Joe Venuti and Jean-Luc Ponty, who transformed the violin into a more versatile instrument, while also drawing on the fiddle players of country music, such as Vassar Clements and Byron Berline.

The album features those who would remain his favorite friends and collaborators: pianist Barbara Higbie, mandolinist Mike Marshall, and violinist Dave Balakrishnan, all musicians from the Grisman circle. With them, Anger forms one of the first neo-acoustic ensembles in Berkeley, Saheeb.

His meeting with the young Balakrishnan is officially commemorated by a duo album, Jazz Violin Celebration; but Anger's principal collaborators remain, for a while, Marshall, with whom he records The Duo (June 1982), Gator Strut, and above all Chiaroscuro, and Higbie, co-credited on Tideline (February 1982) and Live At Montreux (July 1984).

The first album with Marshall is largely the latter's brainchild. With the sense of humor that has always accompanied them, Anger and Marshall launch into a handful of effervescent and spectacular duets: the breakneck Rotagilla, swinging and folky; Wall Of Mando Madness, imbued with Gypsy exhilaration; the somewhat neurotic bluegrass gallop of Free D; and the exhilarating quadrille for two violins, N.K.F. The album closes with the long, spacious Gator's Dream for violin and mandocello.

Tideline is perhaps the album that marks the beginning of his greatest period. From the syncopated title track to the melodious lullaby of Keep Sleeping, from the exotic Onyame to the swinging Gualala, Anger and Higbie demonstrate absolute mastery of orchestration and inexhaustible imagination in their arrangements. Lifeline also attests to their ability to tackle more experimental scores.

Chiaroscuro represents a peak of Anger's chamber folk-jazz, and of all that would follow. The air of Beloved Infidel, in which the violin cavorts with the ensemble (Manring on bass, Higbie on synthesizer, Marshall on guitar), the lively Carolina dance of Piacenza, the driving virtuosity of Coming Back, and the touching ballad Spring Gesture rank among the milestones of acoustic music. Marshall sketches complex scores. Pieces such as Dolphins display classical poise, yet at the same time give themselves over to folk flourishes, thereby fusing vital energy with learned concentration. Dardanells grafts hints of folk melodies onto that glittering network.

Live At Montreux is the dress rehearsal for Montreux, which would be born shortly afterward. Marshall plays guitar and mandolin. The quintet sketches the Caribbean poems Egrets and Egypt, but makes history above all for the fluidity with which it fuses jazz and folk elements, for its three-voice formation (guitar, violin, and piano), whose players never step on one another's lines, for the formal elegance of its execution, and for the composure of its improvisations in short, for an approach to the material that owes more to classical music than to popular music. The long jam In What Hour is its spiritual and formal manifesto. Anger and company nevertheless remember their unorthodox origins, and their sense of humor, when they launch into the reckless, rollicking harmonies of Near Northern.

Anger, Higbie, Marshall, and Michael Manring formed Montreux in 1984, releasing two albums. This quartet, which fused country, jazz, classical, and pop themes, was one of the seminal events in the history of acoustic new age music. A few years later, Anger and Balakrishnan formed the Turtle Island String Quartet (July 1987) with cellist Mark Summer and violist Irene Sazer, taking the reformulation of the acoustic paradigm even further, in a more learned and austere spirit.

Anger's Heritage (Six Degrees, 1997) features Bela Fleck, David Lindley, David Grisman, Vassar Clements, John Hartford, Sam Bush, Willie Nelson, and others performing traditional tunes in a historical context.

Mandolinist Mike Marshall, who came up through David Grisman's school, recorded albums in collaboration with violinist Darol Anger and pianist Barbara Higbie, with whom he established a standard for all future acoustic ensembles, and distinguished himself as a guitarist with a classical-style picking technique. His masterpiece is probably Chiaroscuro.

Violinist Darol Anger, pianist Barbara Higbie, and mandolinist Mike Marshall, all of them raised in David Grisman's circle and already responsible for a series of solo, duo, and trio works, as well as members of a neo-acoustic ensemble, Saheeb, which lasted only one season, formed Montreux with the young bassist Michael Manring. That quartet, with its fusion of country, jazz, classical, and pop sonorities, was one of the seminal events in the history of acoustic new age music.

The first album, Sign Language, can be considered the manifesto of the entire genre, a manifesto articulated around four fundamental principles: the synthesis of elements from different traditions, reworked and internalized until they flow in a neutral harmonic stream; the spontaneous symbiosis and measured individualism of musicians who are, in effect, four solo instruments; the refined pointillism of the instruments, which transforms arranging into an art in its own right; and the melodic vein that permeates every piece.

The overture Skywriting (by Marshall), one of their signature pieces, airy and propulsive; the devilishly fast Brazilian dance Jacob Do Bandolin (Marshall); the exuberant gospel hymn To Be (Higbie); and the ecstatic canticle Circular Birds (Manring) are examples of joyful, vital music that exudes optimism and confidence from every chord and continually feeds on itself.

The debt to the country tradition is evident in pieces that preserve the simple, genuine, and enthusiastic spirit of rural civilization above all the festive and frenetic title track (by Manring), with Anger's violin unleashed, driving the rhythm as in a bluegrass jam amid an obsessive din of exotic percussion and pounding piano; and Grant Wood (Anger), a delirium of stringed instruments in the proudest tradition of theme-and-variations, plunges headlong into full-blown bluegrass.

But the quartet is also capable of moments of intense introspection, of immersing itself in delicate and moving emotions, as in the piano ballad Sweet Intentions (by Higbie), which the violin and guitar adorn with laments. The repertoire also includes impressionist watercolors such as In The Shadow Of The Blimp, made up of free-form improvisations, raga progressions, and veiled dissonances, as well as Just Walking, the jazziest jam, in which Anger's violin assumes the role of a saxophone. Montreux's radiant music opens boundless horizons for acoustic ensembles.

It is above all the spirit that distinguishes this acoustic music from classical music: the simple, genuine, and enthusiastic spirit of rural civilization transplanted into a typically urban elegance and composure. The virtuosity of the four musicians does nothing but add emotion to emotion, thanks to their refined choice of timbral combinations.

Their method of moderate and relaxed collective improvisation reaches its culmination on the final album, Let Them Say. Marshall triumphs there as a composer of catchy themes, as in the title track, marked by a driving mandolin-and-violin duet; the elegant Mandolin Rising; the delicate madrigal October Wedding, with Higbie's sotto voce solfeggio; the subdued, absorbed, sentimental romance Road To Vernazza; and the free-jazz gallop of Free D (which had already appeared on Anger and Marshall's Duo). Anger, for his part, pays tribute to his country roots with the storybook-like King Sod.

If the two veterans dominate the group's sound, all the contributions are of exceptional quality: Manring composes a melodious western-swing refrain, Astronomics, while Higbie serves up a tender atmospheric ballad, Barbara's Dream, and a classically inflected melody, Finding Time. The exquisite elegance of the arrangements is truly their method. The profusion of melodic lines and counterpoints is unparalleled.

By The Fireside (Windham Hill, 1995) is a far less inspired set of covers. A Love Supreme (2007) is a string-quartet version of John Coltrane's masterpiece.

Mike Marshall recorded Uncommon Ritual (Sony, 1997) in an acoustic string trio with double-bassist Edgar Meyer and banjoist Bela Fleck that performed originals inspired by bluegrass, jazz, blues and world music. Live Duets (2003) documented mandolin duets with Chris Tile. He then delved into Brazilian music, first with Brazil Duets (1996), then with his Choro Famoso (2004) and finally with New Words (2007), a collaboration with Brazilian bandolin player Hamilton DeHoland.

Woodshop (2007) is a collaboration between Darol Anger and Mike Marshall.

Big Trio (2009) was a collaboration with violinist Alex Hargreaves and bassist Paul Kowert.

Have You Ever Been (2010) was the Turtle Island Quartet's foray in rock music, a set of Jimi Hendrix compositions reinterpreted as improvised jams plus the four-movement Tree Of Life, an original Balakrishnan composition inspired by Hendrix but dedicated to Charles Darwin, whose beginning and ending rank among the composer's best. By now the quartet consisted of Mads Tolling and David Balakrishnan on violin, Mark Summer on cello and Jeremy Kittel on viola.

Island Prayers (premiered in october 2023, recorded in may 2025), the first Turtle Island String Quartet album in six years, delivers Balakrishnan's three-movement suite Island Prayers, performed with fellow violinist Gabe Terracciano, violist Benjamin Von Gutzeit and cellist Naseem Alatras.
