With guest appearances appearing to be all the rage for today's electronic pioneers, one often wonders whose career benefits most; the guest singer who seeks much-needed credibility or the techno-boffin trying to sell his wares. Thankfully David Kosten's Faultline has produced what is most important; a top quality album. Having said that, with the likes of Michael Stipe, Flaming Lips' Wayne Coyne and Coldplay's Chris Martin on board, Kosten clearly has a lot of influence. Martin impresses most; his vocals on 'Where Is My Boy?' set against the sound of metal on metal allows the listener a chance to hear him in an environment away from the relatively safe guitar tunes of his usual band. Newcomer Jacob Golden is another star performer; his angelic, Thom Yorke-like falsetto elevates 'Bitter Kiss' to something special. Vitally, Kosten's own instrumental work is up to scratch including the violent drumming from Anthony Christmas on 'Missing' and 'Theme For Half Speed', an eerily beautiful, string-assisted instrumental. For once this is a celebrity-heavy album on which the whole is more than equal to the sum of its parts.
