Following yesterday’s announcement that “Bill Kreutzmann and Locknstep Allstars” and Lettuce have been added to the Lockn’ Festival lineup comes word that Umphrey’s McGee will perform an additional set on the Thursday of the festival.

Not only will UM now play two sets on Thursday, but those sets will interlock with two sets from String Cheese Incident (including the String Cheese & The Gang set) for a seamless night of music. Lockn’ 2014 takes place between September 4 and 7 at Oak Ridge Farm in Arrington, VA featuring the likes of Phil Lesh & Friends, Wilco, The Allman Brothers Band, Tom Petty & The Heartbreakers and Umphrey’s McGee. Tickets are available via the event’s website.
