Few figures in pop music are as polarizing as Dave Matthews. He and his band have been a staple of jam-friendly rock music for a quarter-century, and in the process have become either a beloved live act or an irritating musical aberration, depending on who you ask. I maintain that a lot of the backlash has less to do with Matthews' songs and more to do with the bro-tastic reputation of some of his fans. Musically speaking, Matthews has consistently acquitted himself as a solid songwriter with a penchant for hypnotic acoustic guitar hooks. Those qualities will be front-and-center on Tuesday when he's joined by longtime collaborator and virtuosic lead guitarist Tim Reynolds for an acoustic duo set.
