Mass is the third and last full-length album by the experimental band Grotus.[1][5] The album's sound focuses more on alternative and blues rock than industrial and is perhaps their most accessible recording.[6] The band broke up the same year the album was released.
The St. Louis Post-Dispatch called the album "snot-nosed, sludgehammer rock that comes off like a minor league Wax Trax act," writing that "it flashes with brilliant bits, such as 'Taint Nobody's Bizness If I Do,' which sports out-of-tune piano pounding augmented by sequences and raunchy talk-show samples."[7]Ox-Fanzine called it "just plain boring, a pounding piece of pseudo-experimental alternative rumble."[8]
