In 2008, DMB founding member LeRoi Moore passed away after 17 years as the group's saxist. Since then, Dave Matthews has solidly taken the reins of his band, enlisting old friends like Béla Fleck and guitarist Tim Reynolds for live work and for last year's No. 1 album, Big Whiskey & the GrooGrux King. Expect to hear a wide-ranging set from the ever-popular jam band, including cuts from their eighth album, September's Away from the World. In support are rising Denver newbies the Lumineers, who proffer a rousing brand of nu-folk that will find favor with fans of Mumford & Sons.
