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. 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. It was basically a brand new way of working for Sonic Youth, albeit a challenging one, under the auspices of major Hollywood film production overlords, routing their way into the world of soundtrack scoring. And it all comes at a key time and place. It's no secret that 1986 was a transformative year for the band in many ways. The gravitation to the beloved SST stable, in addition to Steve Shelley, now drumming, certainly gave Sonic Youth a renewed vigor and vocabulary. They were already an international touring machine, and gaining considerable steam with critics (even spinning the heads of detractors who had dismissed their arty downtown boho sensibilities prior to '86's Evol). Their cultdom with fans had concrete roots by this point, and the influences that were swarming in the band's orbit marked an exciting time, where almost any trajectory seemed possible, and they were going for it.
