Sunn O)))

Sunn O))) (pronounced "sun") is an American drone metal band from Seattle, Washington, that formed in 1998. The band is known for an extremely heavy sound that blends diverse genres including drone, black metal, dark ambient, and noise rock, and for very loud live performances. Supported by a varying cast of collaborators, the band was formed by two core members: Stephen O'Malley (also of Khanate and Burning Witch) and Greg Anderson (of Goatsnake and Engine Kid).
