Devotional is a new collaborative album with vocalist and violinist Petra Haden, who first worked with Anderson during his time in Goatsnake, as well as on the second SUNN O))) studio album, ØØ Void.

Devotional is a rapturous and heady offering of wordless vocalizations, droning guitars, and heaviness explored in unexpected and intoxicating ways. Inspirations came from deep listening to Indian classical music, as well as a fascinating look at the chaotic and unbelievable life of Ma Anand Sheela and the Rajneesh community.
