Minuteflag was an experimental jam band collaboration between members of the American punk bands Minutemen and Black Flag.

[1] Their only release, an EP, consists entirely of instrumentals with the exception of "Fetch the Water" which features D. Boon on lead vocals.

[1] Recording took place in March 1985, while Black Flag was in the process of writing and recording Loose Nut at Total Access Studio in Redondo Beach, CA;[2] Minutemen had just completed their Project: Mersh 12" EP at the same studio the month before.

[1] The members involved initially agreed that the material recorded during the Minuteflag sessions would not be released until at least one of the bands had disbanded.

[2] A 12" EP on SST Records as SST 050 came out over a year afterward, by which time Minutemen had disbanded after the car crash death of guitarist/vocalist D. Boon; Black Flag themselves split up later in 1986.
