Catch Me If You Can is Ryan Hanratty. His folk-punk is filled with singer-songwriter smarts that he snarls out with proper emotion. Catch him if you can in Keyport at Sun Moon Studio, 29-B West Front Street, at 6:30 p.m., as part of a multi-artist night entitled “Collective Creativity,” where he will obviously impress with his combination of wit, anger and the rhythmic pulse of his acoustic guitar.
