The free concerts feature five stages of live music, one at Curtis, one at Champa, one at Welton, one in Skyline Park 1, and one at Skyline Park 2, from 2:30 p.m. until 9:30 p.m. on Saturday.

“We have people collecting donations, we have a huge group of volunteers who come out and help us, it wouldn’t be possible without them. We do sell drink tickets, people can redeem those, we’ve got food trucks and vendors, it’s really family friendly. It’s a great way to kick off the Memorial Day weekend,” said Rallis.

There is a little something for everyone at the family-friendly event.

“We’ve got some great bands this year, so we’ve got Mat Kearney coming into town, St. Paul & The Broken Bones, they’ll be touring, opening for the Rolling Stones in a few weeks, we’ve got Moon Taxi, we’ve got some great local bands so we try to have a good mix of everyone who is willing to come,” said Rallis.
