With the launch of what amounts to a mini club tour for Bush, the band began rolling out new material this week, giving fans a taste of what awaits when "The Science Of Things" finally arrives this fall.

When the band took the stage in San Diego on Tuesday, Gavin Rossdale and company debuted a number of new tracks, including "Warm Machine," "Jesus Online," "The Chemicals Between Us," "Forty Miles From The Sun," and "Prizefighter." The ban brought the new songs back Thursday night in Pomona, California and is expected to trot them out for shows in Los Angeles and New York (see "Bush To Join The Donnas, Prince Paul, Others At Digital Club Festival").

The band wrote the new songs for "The Science Of Things," which will mark the band's first album since 1996's "Razorblade Suitcase." The album is expected to arrive in September (see "Bush Confirms Club Gig; Settlement Looming In Label Dispute").
