Posted this after seeing the band in concert. Bass, bass, bass.
They sometimes refer to Sunn 0))) (pronounced "sun" and named after amplifiers!) as sludge metal. There is none of metal's fast paced riffs. This band is all SLOW AND LOW. Bass heads take note. The bass was felt for the entire duration of the show. Unrelenting waves of it. Beautiful, slow and cathartic. Topped off with massive use of smoke machines and the band members all wearing full-length hooded robes that obscured their faces while they played. Perhaps the show would best be referred to as a "sonic experience" than "concert" in the normal sense of the term. But well, well worth it. Their new album Monoliths and Dimensions is excellent, and will put the bass end of your system to the test. Sunn 0))) recommends "maximum volume for maximum effect." And it does have a visceral effect.
