Come hang out under the chandelier at the U.S. Bank Plaza stage on Playhouse Square and listen to the soothing sounds of acoustic classical guitar. A collaboration between the Cleveland Classical Guitar Society and Playhouse Square, the concert series has recently brought players like Erik Man and James Marron to town. Tonight, you can hear Michael Reardon perform with a mix of local guitarists and students. The free show starts at 6 p.m. (Gonzalez)
