The boys are back. After taking 2011 away from touring, the Dave Matthews Band, which has sold more than 17 million concert tickets since it began touring in the early 1990s, is hitting the road once again. The last time the band hit the concert circuit was in 2010, when it sold more than a million tickets and grossed $61.2 million. The 2012 tour will begin May 18 in Woodlands, Texas, and continue throughout the country, ending in Mountain View, Calif., on Sept. 9. The Seattle-based band sold more tickets than any other band in the world from 2000 to 2009, moving 11.2 million tickets. The band has returned to the studio to record with producer Steve Lillywhite, which it worked with on its first three studio albums. The new album is due out later this year.
