Although many venues were at the time operated by Clear Channel Entertainment, individual promoter deals were cut in each market by agents Mitch Okmin at the M.O.B. Agency (No Doubt) and Darryl Eaton at CAA (Blink-182). The summer dates were worked around No Doubt singer Gwen Stefani's work on an Interscope solo record (Love. Angel. Music. Baby.), and her role in the Martin Scorsese film The Aviator (2004). "I was like, 'Gwen, can you give me three weeks?'" said Jim Guerinot, manager of No Doubt for Rebel Waltz, to Billboard. "I would have loved to have had a whole summer of this tour."
Joe D'Angelo of MTV News considered No Doubt's performance largely better than Blink's, writing that "The audience here was wholly under [Gwen Stefani's] spell, given that on this particular night, No Doubt were the best show in town, even if Blink played one hell of a concert."
