Om Live at Pioneer Works

OM is a three-piece experimental doom metal band hailing from San Francisco, California. Formed in 2003 by the rhythm section of Sleep, the group features Al Cisneros, Emil Amos, and Tyler Trotter. Together, they draw from a host of other influences—including psychedelic rock, Middle Eastern folk, dub, reggae, and post-rock—and incorporate musical structures similar to Tibetan, Byzantine, and Ethiopian chanting. Their very name derives from the Hindu concept of Om, referring to the natural vibration of the universe.
