Sunn O)))

The self-described "power ambient" duo Sunn 0))) (pronounced "Sun") were formed in the mid-'90s by guitarists Stephen O'Malley (Khanate, Burning Witch) and Greg Anderson (Goatsnake, Thorr's Hammer). Known for its drone-heavy blend of black metal, dark ambient, and low-tuned noise rock, the band took inspiration from the early works of the Melvins and Earth, the latter of whom inspired some of the group's song titles — Sunn 0))) began as an Earth tribute band in Los Angeles and originally played music under the related name of Mars. Sunn 0)))'s basic approach (droning guitars, feedback, distorted bass, and other sound effects) was laid down on their first two releases, The Grimmrobe Demos (recorded in 1998 but not released until 2000) and 00 Void (recorded and released in 2000), both of which were the first two releases on the Hydra Head Records subsidiary Double H Noise Industries.

In 1998 O'Malley and Anderson founded the experimental doom metal label Southern Lord, which would go on to release albums by Sunn 0))), Earth, Goatsnake, and Khanate, as well as offerings from up-and-coming black metal acts like Wolves in the Throne Room and Striborg. Sunn 0)))'s third album (and first for Southern Lord), Flight of the Behemoth, arrived in 2002 and found the group incorporating a bit of percussion (and even a smattering of vocals) into the mix, a creative path they continued to take on 2003's White1 and 2004's White2. Black One arrived one year later, sporting a sound that recalled the band's early work shot through with a heavy dose of electronics, while 2006's Altar found the duo collaborating with Japanese doom outfit Boris.

The live double album Dømkirke followed in 2008, and the expansive Monoliths and Dimensions (which featured, among other things, a Viennese woman's choir and French horns) appeared in 2009. In 2011, the limited-edition Agharti Live 09-10 was issued, followed by The Iron Soul of Nothing in collaboration with Nurse with Wound. In 2014, the band again participated in a collaborative effort, this time with Norwegian group Ulver on the album Terrestrials, which appeared in February. In addition they recorded a full-length with Scott Walker; Soused was released in October. ~ William York & James Christopher Monger, Rovi
