Keller Williams built his career as a one-man-jam-band. With an acoustic guitar and some looper pedals, he simulates an entire band and improvises over his own playing. Last year he enlisted a band of his own to go on tour with, but this year, it's back to basics. Williams will be at the Ridgefield Playhouse, all on his own, Thursday night, though you might not notice the difference sonically.
The Ridgefield Playhouse, 80 East Ridge, Ridgefield. Thu., May 2, 8 p.m. $37.50. (203) 438-5795. ridgefieldplayhouse.org.
