Black Flag was an American punk rock band formed in 1976 in Hermosa Beach, California. Initially called Panic, the band was established by Greg Ginn, the guitarist, primary songwriter, and sole continuous member through multiple personnel changes in the band. They are widely considered to be one of the first hardcore punk bands as well as one of the pioneers of post-hardcore. After breaking up in 1986, Black Flag reunited in 2003 and again in 2013.

Despite 1984-85 being the most fruitful period for the band and their record label, Ginn and Rollins would ultimately decide to eject Roessler from Black Flag, citing erratic behavior. It has also been suggested that Ginn's accommodating Roessler's college schedule created tension in the band. Her absence, and the lack of a steady drummer (Stevenson quit and was replaced by Anthony Martinez), contributed to the comparatively weak reputation of the last few Black Flag tours. However, the live album Who's Got the 10 1/2 ? shows the evolving line-up, with Kira and drummer Martinez, to be a powerful and entertaining unit. Furthermore, various bootlegs of shows circulating from the 1986 tour, as well as the Dave Markey documentary Reality 86'd, show the Ginn/Rollins/Revuelta/Martinez lineup to be a ferocious and cohesive group.  By 1986, Black Flag's members had grown tired of the tensions of their relentless touring schedule, infighting, and of living in near-poverty. The band had been together almost a decade, and true commercial success and stability had eluded them. The band's erratic artistic changes were a barrier to their retaining an audience - Ginn was so creatively restless that Black Flag's albums were often very dissimilar. At one point, Rollins apparently said, "Why don't we make a record that was like the last one so people won't always be trying to catch up with what we're doing?" The next album, In My Head, with its powerful bluesy proto-grunge-metal, did seem to finally be a cohesive follow-up to their previous album Loose Nut, but it would be their last.  Black Flag played its final show on June 27, 1986, in Detroit, Michigan. In his book Get in the Van, Rollins wrote that Ginn telephoned him in August 1986: "He told me he was quitting the band. I thought that was strange considering it was his band and all. So in one short phone call, it was all over."
