Purcell, who performs every Tuesday at Logan Arcade with the aplomb of a ringmaster and the flair of a standup comedian, specializes in close-up magic. It’s the most intimate show in town: His stage is a small table, with room for just two spectators. Cast a skeptical eye on his card and coin tricks, but prepare to be flummoxed by impossible-to-explain maneuvers, like when he asks you to sign a $20 bill, burns it, and then finds it, unscathed, inside a lemon swiped from the bar. 2410 W.
