One (Un) is a group featuring Marcia Bassett (Double Leopards), Tara Burke (Fursaxa), Grant Acker, and Tom Roach. They had two releases on the Siltbreeze label before disbanding in 1999.
The cassette release has two side-long practices that are actually worth hearing. Messy and incoherent, UN sounds as if recording only takes place after long bouts of sleep deprivation, but few can match the utter desolation of this deceptively simple music.
