OM is a duo from San Francisco, California, United States, formed in 2003 by the rhythm section of the stoner metal band Sleep. The band's first three albums feature Al Cisneros on vocals and bass and Chris Hakius on drums. The band's music is similar in structure to Tibetan and Byzantine chant and is rich in rhythm and melody. Their music and lyrics lift off at the beginning and slowly mutate giving a feeling of evolution inside each song. The vocals have a monotone quality, producing, on some tracks, a noticeable hypnotic effect of the sort that tends to be appealing to the devotees of the many various genres of druggishly-bent, "space" music - but which not all music calling itself stoner rock necessarily is able to cause. On January 2008, Hakius left the band and was replaced by drummer Emil Amos, of Grails. OM have since released Gebel Barkal, a 7" for Sub Pop's Singles Club, a live vinyl-only LP titled Conference Live on Important Records, and on September 2009 their fourth full-length studio album God is Good was released by Drag City. On May 2011 Drag City confirmed on their website that the band was working on a new album, titled “Advaitic Songs”, which was released in June of 2012 and met with critical acclaim.
