One of the crucial bands in the "Nardcore" scene that arose in the 1980s, Dr. Know are a Southern California punk group who were among the first to add metal influences to their high-speed skate-punk attack. Noisy, thrashy, and not afraid to be rude, the band's raw early recordings earned them a potent cult following. They pushed their metal undertow closer to the surface when they signed to the maverick metal label Death Records for 1986's This Island Earth and 1988's Wreckage in Flesh, though their fury and irreverence was essentially the same. 2001's Habily: What Was Old Is New (aka F**k Off and Die) saw a latter-day version of the band re-recording some of their best-known material.
