Saw Psycho-A-Go-Go, a local band (from the Hershey-area, I think) at ABC the other week.
Great show, nice mix of punk, rockabilly, and garage. The crowd wasn't huge, but what else can you say about a town that loves cover bands.
Also, check out Jesse Vital, local artist and punker. I was lucky enough to have Jesse serve my fiancee and I at Blue Pacific in Lancaster a few weeks ago. We both remembered him from various open mic nights back in the day. Cool guy, interesting artwork, and unique songs.
