Stop. Look. Listen.

This will be a deep blue Friday in Lancaster, with the Chameleon Club’s Blues Fest, with Johnny Winter, the Nighthawks, Blue Light Special & Ragtime Willie, starting at 7, and the last installment of the Lancaster Arts Hotel Gallery’s Midwinter Bluesfest, featuring the Billy Penn Project, starting at 5. The gallery also will be opening an exhibit of digitally solarized photographs by Milt Friedly of rodeo scenes in Wyoming, his home state. If that doesn’t fill up the evening, there’s Music Friday, with performers all over town.
