CHILLICOTHE — Friday may have been the first day of winter, but jam band fans got the first hint of warmer weather with the debut lineup for the Summer Camp Music Festival at Three Sisters Park.

The 19th annual installment of nonstop live music on multiple open-air stages throughout the Memorial Day holiday weekend features daily performances from stalwarts Umphrey's McGee and moe. Also at the top of the ticket are Big Gigantic, Zeds Dead and genre-crossing entertainers such as Blues Traveler and George Clinton and Parliament-Funkadelic.

The first-round lineup announcement lists more than 50 performers, but more than 180 artists will perform on nine stages during the festival, with later announcements planned to reveal those acts, including an artist with top billing for a Sunday show that is open to single-day ticket sales.

Festival producer Jay Goldberg Events & Entertainment noted in the Friday announcement that early bird tickets had already sold out, but additional tickets with early-bird pricing will be available through 11:59 p.m. Christmas Eve online at or by phone at (800) 514-3849.

Festival grounds open to campers who pay additional fees on May 23, with three-day passes from May 24 through May 26 currently on sale at the early-bird price of $189.50 per ticket.
