Blue Man Group is a wildly popular performance collective whose showmanship can be seen everywhere, from off-off-Broadway to Intel Pentium Microprocessor commercials. The Complex, which follows the act's previous recording (Audio), features Blue Man's trademark homemade tubular instruments and ferocious undercurrent of percussion—as well as an impressive parade of guests. Dave Matthews supplies wry and deadpan lyrics to "Sing Along," a track that features production by Dan the Automator. Esthero makes a welcome return on a cover of Jefferson Airplane's "White Rabbit." And Nashville-based electronic trio Venus Hum injects new life into the Donna Summer classic "I Feel Love." While the numerous guest spots are interesting, the most compelling music is the instrumentals featuring the complex and highly nuanced Blue Man sound.—MJ
