Filthy from the ground on up

Dirty Filthy Mud: "The Forest of Black" (Worex, 1968)

According to my homeboy Vernon, Dirty Filthy Mud were from Oakland and only had one release, the single pictured above. I've never seen a copy of it, but "Forest of Black" has been bootlegged a bunch of times; the bootleg I have features both sides of the single. The other side, "Morning Sun Flower", is folk-rockish but on this track they really knock the psych + electronics steez of Fifty Foot Hose and United States of America out of the box.
