Super fun to check out!
Tip: Bring a folding/collapsible chair because all the good seats fill up an hour or two before the show starts, plus all the surrounding chairs get filled too.
They have some good bands and they're all different, so they have a concert for every taste in music.
If you do go to Music in the Park, it's really awesome to help out the local businesses and buy dinner somewhere nearby before/after the show. The local businesses can make SO much money in one evening when everyone comes out to the concert and buys something. It's such a great boost for the local economy.
