Thuja were part of San Francisco’s Jewelled Antler collective. The collective grew out of a concern that independent music was stagnating. Glenn Donaldson, Loren Chasse, Steven R. Smith and Rob Reger formed Thuja, taking a step back from the instrumental rock groups they had been part of such as Mirza. They found new hope in improvisation, weird folk, field recordings and home recorded experiments played on broken instruments and items that you couldn’t really call instruments. 'Hills' was originally released in 2002.
