Sunn O)))

is an experimental drone metal band formed in 1998 by Stephen O’Malley and Greg Anderson. Known for their monumental soundscapes, they blend heavy, sustained guitar tones with elements of doom, noise, and dark ambient. Their immersive, ritualistic performances and acclaimed albums like 'Monoliths & Dimensions' have made them pioneers of the genre, pushing the boundaries of heavy music and redefining sonic experimentation.
