Last night at a Steeler's Game Watching Party/Free Concert/Free Hot Dog Festival, I saw two bands.
Nik and the Central Plains: I know Nik from the open mic nights. His music is great. It's like super weird folk music, but is very catchy.
Aloud: Aloud was your more straightforwad modern rock band, but they were pretty good. The were from Boston, MA, and had a good "wall of sound" thing going.
