The sparingly named Om reunites the oft-heralded Sleep rhythm section of Al Cisneros (bass, vocals) and Chris Haikus (drums); but this time, rather than producing monolithic stoner/doom metal, the duo is focused on a softer, if no less hypnotic brand of drone rock, partly infused with monastic and Tibetan chanting. Since reconnecting in 2004, the duo has released its epic sonic meditations in the shape of split EPs with the likes of Current 93 and Six Organs of Admittance, and albums like 2005's Variations on a Theme, 2006's Conference of the Birds, and 2007's Pilgrimage.
