In 1984, California hardcore legends Black Flag ended a short period without new music by releasing three records in one year. The final album of the year wasSlip It In,the band's fourth record. It was very different from their earlier material but the boundaries they pushed were the ones they had created just a few years earlier. The lineup for Black Flag at that time was Henry Rollins, Greg Gin, Kira Roessler, and Bill Stevenson. And, of course, the record featured iconic album art from Raymond Pettibon. This vintage Black Flag shirt from the early 2000s, nicely faded and worn, features the album art to 1984's Slip It In.
