Umphrey’s McGee announced on Wednesday that guitarist Jake Cinninger will miss the band’s weekend performances at SweetWater 420 Fest in Atlanta, GA. The now-quintet is set to perform three shows throughout the weekend, including the Thursday pre-party and a late-night headlining show at the Variety Playhouse on Friday.

In a post to the group’s Facebook page, Umphrey’s stated that Cinninger will take “some necessary time to work on his health and well-being.” The remaining lineup of Brendan Bayliss (guitar, vocals), Ryan Stasik (bass), Joel Cummins (keyboards), Kris Myers (drums), and Andy Farag (percussion) will perform mainly as a five-piece as well as “welcome a handful of guests throughout the weekend.”

Umphrey’s McGee will kick off the festival at Atlanta’s Centennial Olympic Park on Thursday with an “All Night Wrong” cover set featuring special guests, in addition to a preceding TAUKing McGee set. The Thursday pre-party will also host performances from Empire Strikes BrassOteil & Friends, and two sets of The String Cheese Incident. Umphrey’s McGee signed on for the pre-party earlier this month after Warren Haynes injured his shoulder, forcing Gov’t Mule to cancel its set in the slot originally vacated by moe. following Chuck Garvey‘s stroke in November.
