The slow-burn sounds of Sonic Youth's 1986 rehearsals to score Ken Friedman's spooky highway film Made In USA are yet another mile marker in the band's long and varied existence, now being issued as Spinhead Sessions (named for the North Hollywood studio used by SST label acts like Black Flag and Painted Willie). These jams were later built upon for a full-on (and quite different) soundtrack production, but the rough sketches here find the band taking time with truly new and introspective sound worlds. PREVIOUSLY UNRELEASED.
