The Disco Biscuits will return to Colorado this April for Bisco Inferno, featuring three shows at Denver’s Ogden Theatre and most notably, one show at Red Rocks with special guests Bill Kreutzmann and Mickey Hart of the Grateful Dead. The shows are set to take place April 15-18, the 17th being the show involving the Rhythm Devils at Red Rocks.

The announcement signaled the growing relationship between the Biscuits and Kreutzmann and Hart, especially for Bisco keyboard player Aron Magner, who has been involved in several of Kreutzmann’s recent projects, including Kreutzmann’s LockNStep Allstars at LockN’ Festival, Billy & The Kids at Warren Haynes’ Christmas Jam, well as the Biscuits/Rhythm Devils’ performance at last summer’s Gathering Of The Vibes.

Presale tickets for the shows are available here.
