XPN welcomes legendary blues musician Charlie Musselwhite to The Sellersville Theater tonight. Over his almost 50-year career, Musselwhite has released over 20 records in addition to collaborating on efforts by Bonnie Raitt, Tom Waits and others. Following the success of his 1966 debut, the 2010 Blues of Fame inductee moved to San Francisco where he and his unique blues-harp playing stood out against the counterculture backdrop. Most recently, Musselwhite collaborated with Ben Harper for 2012′s Get Up!. Tickets and information for tonight’s all-ages show with Deb Callahan can be found here. Below, watch Musselwhite perform “Blues Why Do You Worry Me?” live.
