A prime house-pop group and consistent club act, Faithless is at its core a duo of producers Rollo and Sister Bliss. Before the group officially came together in 1995, Rollo had produced a previous club hit ("Don't You Want Me" as Felix in 1992), plus an album for Kristine W. and remixes for the Pet Shop Boys, Björk and Simply Red. Sister Bliss, a piano and violin prodigy from the age of five, converted to acid house in 1987, and quickly became one of the UK's best house DJs, also recording several singles as herself.
