Dave Matthews Band, DMB for short, was formed in 1991 and has since become one of the most influential rock groups of all time. Hailing from South Africa, Matthews put the project together in Charlottesville, Virginia, with prominent musicians from the area such as Carter Beauford and LeRoi Moore; the impact of country music and jazz is detectable in the band’s greater sound. With a tinge of grunge and pop as well, the product is all-encompassing and one that bodes well for the beautiful Jones Beach Theater, with the water and breeze at their back. With more than 25 million tickets sold since its start, DMB is the second largest ticket selling band in history. Clearly, this ticket’s worth a buck or two. —Henry McGrath
