With Roessler on board, Black Flag began earnest experimentation, sometimes to critical and audience disdain: One critic writes that "Slip It In" "blurs the line between moronic punk and moronic metal"; another writes "My War" is "a pretentious mess of a record with a totally worthless second side." Rollins reports that Black Flag's set-lists in this era rarely included older crowd favorites like "Six Pack" or "Nervous Breakdown", and that audiences were often irritated by the new, slower Black Flag. Violence against the band (and especially Rollins) was ever-present, although the vocalist was now an avid weight lifter, and more than able to defend himself. Furthermore, to Rollins' chagrin, Ginn's interest in marijuana steadily increased; as Rollins put it, "By '86 it was 'Cannot separate the man from his Anvil case with a big-ass stash.'" Despite the initial resistance to the new music and quasi-psychedelic direction, "My War" would later be cited as a formative influence on the grunge, stoner and sludge metal genres. The band would continue to evolve toward a more heavy metal sound, with 1985's "Loose Nut" featuring more polished production.
