Since Umphrey’s McGee won’t be able to put on a traditional New Year’s Eve concert this year, they have elected to put on one from a past year instead. On January 1st, 2021, the prog-jam outfit will air their December 31st, 2010 concert from The Rivieria in their native Chicago on, the band announced on Tuesday.

The marathon, three-set concert has never before been released, despite Umphrey’s classifying it as “one of the most requested shows” in a press release. Clocking in at over four hours, the evening saw the debut of the original “Deeper” as well as the band’s first-ever takes on James Brown‘s “The Payback” and “Get Up (I Feel Like Being A) Sex Machine”, The Police‘s “Demolition Man”, Beck‘s “Mixed Bizness”, Radiohead‘s “The National Anthem”, and Stevie Wonder‘s “Sir Duke”.

In addition to the myriad of debuts, December 31st, 2010 also saw Umphrey’s joined by a rotating cast of special guests. These included Mad Dog and his Filthy Little Secret Horns comprised of Michael “Mad Dog” Mavridoglou on trumpet, Jeff Coffin (Dave Matthews Band) on saxophone, Chris Neal on saxophone, and Brent Sanders on trombone, in addition to Cody Dickinson (North Mississippi Allstars) on washboard.

This night of music was noteworthy beyond the music as well, as the band brought a decade’s worth of New Year’s Eve celebrations in Chicago to a close. The tradition began in 2000 with a show at The Cubby Bear and kept going strong through 2010. Umphrey’s had originally intended to release the show in 2011, but stated that “the inertia of touring continued and the tapes descended into the archives.”

Tune in on January 1st, 2021 at 8 p.m. ET to see Umphrey’s McGee’s long-sought-after New Year’s Eve concert from 2010 at The Riveria in Chicago. Tickets are available here and special throwback merch is available at checkout. The show will be available for on-demand replay for 48 hours after the initial airing.
