Sunn O))) (pronounced sun) is an American experimental band that incorporates some elements of the ambient, noise and black metal genres. The band consists of Stephen O'Malley (also of Khanate and Burning Witch) and Greg Anderson (of Goatsnake). Their sound image is extremely slow and heavy, using electric guitars, in low tunings such as drop A, enriched by resonant feedback creating their soundscapes. There is very little drumming and a lack of any discernible beat.
