AJ Srubas plays multiple styles of traditional fiddle, including early bluegrass. And he’s got some of his early bluegrass buddies from his southern travels in a series of shows coming up. The players are banjoist Trevor Holder, guitarist Conner Vlietstra, mandolinist Reed Stutz and local bass player Rina Rossi. On November 15, the quintet plays at the Oak Center General Store, November 16 in Cambridge, and November 20 in Minneapolis. In a conversation with Phil Nusbaum, A.J. talked about his love of early bluegrass fiddle music.
