There are patty melts and tuna melts but, this week, St. Louis got a taste of U-Melt, a jam band that has garnered Internet buzz in recent years for its sprawling sets and wide-ranging influences. The band performed at the Broadway Oyster Bar on Thursday. Rob Salzer, U-Melts' indefatigable lead guitarist and vocalist, talked to The University News about his affinity for the road, U-Melt's stylistic leanings and the perilous state of the global environmental crisis.
