See the "Bishop Allen w/ Hotel Lights" thread I made last week,
but you can add a BA show with Hotel Lights in Chicago on the 18th.

Also, I saw Chris Mills open for Ben Folds in April, and I was less than impressed. He had this goofy grin on his face the entire time. It was just a single guy rocking out with an electric guitar.

Hotel Lights is fronted by the former drummer of Ben Folds Five. It's quieter music. I haven't heard much of it.
