Faithless is to house what Massive Attack is to trip-hop--that is, both acts expand the boundaries of their respective styles while creating a fascinatingly dark atmosphere. Formed in London during the mid-1990s, Faithless is, at its core, producers Rollo and Sister Bliss, with rapper/vocalist Maxi Jazz fronting the group. The FOREVER FAITHLESS collection cherry-picks from the ensemble's 1996-2005 catalogue, mixing tracks in a non-chronological order that showcases the band's consistency. "Insomnia," one of Faithless's biggest club hits, kicks off the set with its pulsing house beats and ominous synth lines. Other highlights include the dramatic dance-floor epic "Salva Mea," the Nina Simone-sampling "I Want More," and the dreamy "One Step Too Far," which features the ethereal vocals of Dido, who got her start as a backing singer for Faithless (and is Rollo's sister). Listeners seeking an excellent introduction to this influential group should look no further than FOREVER FAITHLESS.
