Call them a jam band or whatever you want, but the genre-hopping, seemingly indestructible Dave Matthews Band are the world's hardest working live act. Last year, they sent shock waves throughout the nation's frat houses by finally taking a much-deserved touring hiatus – the group's first break from live performance since their formation back in 1991. Even when the band's longtime woodwind master LeRoi Moore died following an ATV accident in 2008, they played a show the day he died. In a number of ways, 2012 is a year of new beginnings for the Dave Matthews Band. They're back on the road for a summer-long tour, and their still-untitled eighth album (on which the group reunites with veteran producer Steve Lillywhite) is set for release this fall. Assuming you can handle the sight of some shirtless swaying dudes and the odor of a few weed clouds, the Dave Matthews Band is a must-see group in a live setting, where the songs bloom and breathe, aided by groovy improvisation and more muscle. 7 p.m. Tickets: $40.50 and $75..– Ryan Reed
