The Dave Matthews Band finally caught a breather in 2011, limiting their touring to four single-stop festivals.  But this year the veteran rockers will regain their crown as one of the summer’s top touring draws.  The group will do the usual, employing a wide array of opening acts to show off their varied musical tastes to their loyal fanbase.  Edward Sharpe And The Magnetic Zeros, The Head And The Heart, Mariachi El Bronx, Carolina Chocolate Drops, Blind Pilot, Lettuce, Fitz And The Tantrums, Gary Clark Jr., Delta Spirit, Brandi Carlile, SOJA, Tower Of Power, The Avett Brothers, and The Allen Stone will all take turns opening shows.  This year’s trek begins May 18th in Woodlands, Texas.  Tickets go on sale at www.warehouse.davematthewsband.com today at 10:00AM ET.
