Behind their wall of art rock, they might be closet metalheads. "Washington Monument" would fit in your favorite stoner band's set list. "The Red Human-Headed Bull" slides down a deep groove, from guitar arabesques to frantic metal fretwork. The album ends with a string of performance-art suites. The group's live shows are intricately edited multimedia presentations that synchronize with the music. Stripped of that visual presentation, Infinite Number's music is just as evocative.
