Dave Matthews Band had the highest-grossing tours of the 00s and U2 had the top tour of 2009, says Pollstar, which covers the concert industry.
Is it too cliche to say DMB shows were green in more ways than one? In 2009, for instance, the "So Much To Save" tour encouraged fans to recycle and volunteer, diverting more than 42,000 pounds of waste from landfills.
Dave's tour also was managed by MusicMatters and the band's Bama Green Project, a partnership between groups including Reverb, also featured on this site in 2009 for its efforts to help artists green their tours.
