Definite DECIBEL Debris

Since 1981, Phoenix, Arizona metal overlords Flotsam and Jetsam have been serving up the molten jams to the underground thrash scene. Over the course of a dozen full-lengths and equal onslaught of singles and EPs, the band has remained a lesser-known but critical element to the American heavyweight music scene. The band has undergone some major lineup changes throughout the years (founding bassist Jason Newsted split the band in ’86 to join Metallica), but vocalist Eric A. ‘A.K.’ Knutson is currently keeping the band on track in carrying on their loud and brutal legacy.

7 p.m. Saturday, Nov. 26 with opener Hatchet, Jack Rabbits, San Marco, $15,
