Irish band Lunasa hits the Arcata Playhouse tonight! This is a serious opportunity to see the festival headliners in an intimate venue. In addition to being fine musicians of the Celtic persuasion, the band members have a sense of humor befitting the theatrical space — when last at the Playhouse in 2012, they took a break only to reappear in costumes they came across backstage. Frontman Kevin Crawford (flute/whistle) is reputed to be especially hilarious. $20, $18 students, with music at 8 p.m.
