Umphrey’s McGee will now perform two headlining sets at the four-day event, which is set to take place at its new home at Coopers Lake in Slippery Rock, PA on September 19th-22nd. The festival had previously-announced its initial 2019 lineup late last month, with scheduled performances from Tipper (two nights), Tycho, Papadosio (4 sets), Black Moth Super Rainbow (2 sets), Keller Williams (3 sets), Goose (3 sets), Lapa (2 sets), The Polish Ambassador (2 sets), CharlesTheFirst, and more.

Members of Umphrey’s will have a busy weekend as Doom Flamingo, the retro-themed synthwave rock outfit co-founded by bassist Ryan Stasik, and The Omega Moos, a supergroup comprised of Umphrey’s guitarist Brendan Bayliss, Stasik, The New Deal keyboardist Jamie Shields, and drummer Nick Blasky, will both perform throughout the weekend as well. The Omega Moos recently reunited for a special late-night show following an Umphrey’s performance in Detroit, MI back in late February.

Tickets to the end-of-summer festival can be purchased here. Fans are encouraged to purchase tickets before the cost of admission raises in price at midnight on August 2nd.
