Unlike "Audio", "The Complex", released in 2003, featured a variety of vocalists and guests including Tracy Bonham, Dave Matthews, Gavin Rossdale and Venus Hum. The record spawned its own 2003 tour, "The Complex Rock Tour," the first headlined by Blue Man Group. The tour deconstructed the traditional rock concert experience into its often clichéd parts and was chronicled in a 2004 DVD release. The tour featured Tracy Bonham and Venus Hum as supporting acts. The DVD included a surround sound mix of some of the studio recordings.
