Sunn O))) is an American drone metal band from Seattle, Washington that formed in 1998. It is mainly known for its synthesis of diverse genres including drone, ambient, noise, and extreme metal. Supported by a varying cast of collaborators, the band was formed by two core members: Stephen O'Malley (also of Khanate and Burning Witch), Greg Anderson (of Goatsnake and Engine Kid).
Sunn O))) is named after the Sunn amplifier brand, whose logo includes a circle next to the &SUNN& banner with waves heading off to the right. In interviews, Stephen O'Malley stated that the name was also chosen as a play on the name of the band Earth, pioneers of drone music throughout the 1990s, reasoning that Sunn revolved around Earth. Before the band members moved to Los Angeles, the duo briefly used the moniker Mars.
The band's sound image is extremely slow and heavy, using electric guitars, in low tunings such as drop A, enriched by resonant feedback creating its soundscapes. There is very little drumming and a lack of any discernible beat. When performing live the band wears robes, fills the air with fog, and plays at an extremely high volume.
The band releases the majority of its music through the label it founded in 1998, Southern Lord Records. However, the band released ØØ Void, its second album initially on Rise Above Records and Hydra Head Records, and Dirter Productions, with the latter pressing the album as a double vinyl. The Grimmrobe Demos was first released also on Hydra Head Records. It was later issued as a double picture record set by Outlaw Recordings and finally reissued by Southern Lord in 2004.
Sunn O))) experiments with a variety of styles and sounds, progressing the primarily guitar and bass style of The Grimmrobe Demos and ØØ Void. On White1 and White2, Sunn O))) noticeably expanded on conceptualization by inviting several guests (see collaborations below), resulting in everything from quiet meditative ambient sounds (&A Shaving of the Horn that Speared You& from White1) to a bizarre bass experiment track (&bassAliens& from White2). Black One continued this direction, utilizing far more electronics, synthesis, and other instrumentation than earlier Sunn O))) material, yet still marking a significant return to its traditional sound.
Sunn O))) is widely regarded as leaders in its genre, including by The New York Times Magazine of May 28, 2006, when the band was written up in an article called &Heady Metal& by John Wray. It was praised in an issue of Wonkavision, an independent music magazine, as one of the greatest modern metal acts. Sunn O))) was also shown in the August 2007 issue of Q Magazine (the &loud issue&), with its album White1 being named the 18th-loudest album of all time, just above AC/DCs Back in Black and below Jimi Hendrix's Are You Experienced?
In 2008, Sunn O))) released its live album Dømkirke, and also announced that it would do a mini-tour consisting of four concerts to commemorate the group's 10th anniversary to coincide with release of The Grimmrobe Demos.
The band's seventh studio album, Monoliths & Dimensions, was released on May 18, 2009, and was acclaimed by both press and public alike.
On December 17, 2009, the song &Hunting & Gathering (Cydonia)& from the CD Monoliths & Dimensions was named the Heaviest Song of All-Time by Jason Ellis on The Jason Ellis Show on Sirius/XM. Greg Anderson then appeared on The Jason Ellis Show on January 12, 2010.
The band played the ATP New York 2010 music festival in Monticello, New York, during September 2010, where it collaborated with Boris to perform the Altar album live.
For live performances, Hungarian-born Attila Csihar (Mayhem) has performed as the primary vocalist since 2003.
Sunn O))) will be releasing a collaboration album with Ulver, entitled Terrestrials, in February 2014.
