Mnemosyne features Aidan Baker on guitars/vocals, Richard Baker on drums/percussion and Heather K. (replacing original member Rodin Columb) on bass/electronics. Collaborators in various other projects, they finally formed their own band in late 2002 to explore, within the context of a 'power trio,' fragmentary post/space-rock ranging sonically from washes of ambient sound to walls of fractured dissonance.
