A one-time collaborative recording project between the entirety of the then current Black Flag and Minutemen lineups which took place March 3rd, 1985 at [l=Total Access Recording Studios]. The members involved initially agreed that the material recorded during the session would not be released until at least one of the bands had disbanded. [l=SST Records] made the results available as an EP in December 1986, a year following D. Boon's death, which had ended Minutemen. Black Flag had split up in August 1986.
