"When you woke up, I guess you didn't know I would steal you from your girlfriend," sings Daníel Ágúst Haraldsson in what is the most striking opening lyric to an album I've heard in a while. GusGus, Icelandic veterans of artsy techno music, have always enjoyed provoking their audience, and when they do so here, it's exhilarating. Obnoxiously Sexual is exactly that, its frayed synths, skittering hi-hats and rasping brass careening into your personal space. Another Life continues the thrust with a murky, manipulated vocal that sounds as if it was sung through a gimp mask. God Application has a twist of neo-soul but lyrics that sing of "an attraction, a perversion, dominating someone else is perhaps a nature in itself". It's dirty, off-kilter and exciting, but sadly GusGus can't keep it up. This Is Not the First Time sounds like Faithless did a decade ago, Mexico is six and a half minutes of low-level squelching, and closer This Is What You Get When You Mess With Love sounds like the answer is "wishy-washy ambience". If you were the guy who got stolen, by the end you might be hankering for your girlfriend again.
