Sunn O))) is an American drone metal band that has carved out a unique niche in the heavy music landscape since their formation in 1998. Hailing from Seattle, Washington, the duo, consisting of Stephen O'Malley and Greg Anderson, is renowned for their extraordinarily heavy and slow sound that melds elements of doom metal, drone, black metal, dark ambient, and noise rock. Their live performances are legendary, often reaching deafening volumes of around 120 decibels, creating an immersive and intense experience for the audience. With eight studio albums to their name, including the critically acclaimed "Pyroclasts," Sunn O))) continues to push the boundaries of heavy music, delivering a sonic journey that is as powerful as it is atmospheric.
