Grand Opening and Closing

Operating as both a musical ensemble and an apocalyptic performance art collective, Sleepytime Gorilla Museum utilized an array of custom-built, bizarre instruments to achieve their singular sound. 'Grand Opening and Closing' is a theatrical barrage of jagged avant-metal riffs, complex rhythmic interplay, and macabre, vaudevillian vocals. The album's unsettling and entirely unpredictable architecture defies easy categorization, standing as a landmark of modern avant-prog.
