Claude says:The Complex arrived as Blue Man Group's most song-driven record, bringing in guest vocalists and tackling covers like Donna Summer's "I Feel Love" alongside originals — all while keeping their signature handmade percussion rigs and thundering rhythms intact. You latched onto it in late 2006 and spun it hard through 2007, particularly drawn to the covers ("I Feel Love," "White Rabbit") and the relentless grooves of "Piano Smasher" and "Up to the Roof."
