I saw Ted Leo and the Thermals in the basin of a drained, gigantic community swimming pool in Brooklyn last summer.
It was amazing.
This summer looks to be the last one filled with concerts for the pool (at least for a while) as the McCarren Park Pool is undergoing some rehab on the order of $50mil.
Paid concert series schedule here.
Get planning on that day trip kids. The venue is unique and worth it.
