July 5, 12, 19, & 26 – Blues 1.0 is a four-session class that’s both a history and an appreciation of that musical genre. Charley Walters programs and hosts Island Blue Notes, a blues and jazz show on 89.5 WNCK and 97-7 ACK-FM. From 1982 until 2006 he owned Musicall (the island’s only music store), and in the 1970s he reviewed records for Rolling Stone and The Boston Phoenix. Free admission, registration requested.
