The most successful of the new jack swing artists were Philadelphia's Boyz II Men, who established their "hip-wop" style (new jack swing plus four-part harmonies a` la doo-wop) with Cooleyhighharmony (1991), produced by Michael Bivins of the New Edition, and churned out colossal hits such as the Babyface-penned End of the Road (1992), that broke a record held by Elvis Presley since 1956, I'll Make Love to You (1994), another Babyface creation (which even beat the previous record), On Bended Knee (1994), produced by Jimmy Jam & Terry Lewis (a hit which beat their own record), and One Sweet Day (1995), a duet with Mariah Carey (which, again, broke their own previous record).
