Mattress is a strange beast. The solo project of Portland musician Rex Marshall defies easy categorization. Commanded by Marshall's Calvin Johnson-esque deep, deep baritone, there's a languid sensuality to the music that somehow finds a middle ground between a lascivious crooner and the dirty, desolate electronics of Suicide. In terms of sexual menace, Mattress is what might play on the loud-speakers in the basement beneath This is Hardcore-era Jarvis Cocker. Yes, there's a beat, but even the drum machine sounds weary, going through the motions like two adulterous lovers who've sunken too far into an emotionally draining affair. Marshall, meanwhile, sometimes comes across like the ghostly remnants of David Bowie's bleariest descents into '70s decadence. Listening to Mattress leaves you feeling filthy and electrified, full of self-loathing and too much self-love.
