Oslo, Norway, August 10th, 2008. Following their 200th gig, playing before 2000 people at the Oya festival, SUNN O))) teamed up with Norwegian legends ULVER at their Oslo studio, Crystal Canyon. They recorded three "live in improvisation" pieces, starting that evening and ending at dawn, as Northern sunlight seeped in through the windows. "Terrestrials"; is three movements which are fluid like the flow of magma beneath the Earth's crust, sonically uninhibited, unpredictably cosmic, haunting and stirring yet simultaneously ceremonious and beautiful.
