Following this weekend’s news that Bob Weir has cancelled all of his upcoming live performances, Lockn’ has made a major lineup announcement. Due to Weir’s absence Furthur will no longer perform on Friday. Instead, a new special collaborative project will debut, Bill Kreutzmann and the Locknstep Allstars. Lockn’ co-founder Peter Shapiro explains, “When we found out that Bob Weir wouldn’t be able to make it this year, we decided to keep it all in the family by asking his brother Bill to join us at Lockn’. We are all looking forward to the premiere of Bill Kreutzmann and the Locknstep Allstars. For those of you who are curious just what Locknstep is, join us in September and we’ll all find out together.”

Three additional acts have been confirmed for this year’s event. Thursday’s lineup will feature some old school funk with the rousing sounds of Lettuce. The summer-long Rockn’ to Lockn’ competition concluded over the weekend adding two Virginia-based groups to the main stage schedule: People’s Blues of Richmond will kick off the music on Friday, while Erin & The Wildfire will do the same on Sunday.

Lockn’ will return to Arrington, VA on September 4-7, featuring Tom Petty & The Heartbreakers, The Allman Brothers Band, Phil Lesh & Friends, Wilco, Widespread Panic, The String Cheese Incident, Willie Nelson, Tedeschi Trucks Band, Umphrey’s McGee, Grace Potter & The Nocturnals and many others. Both single day tickets and four day passes are available.
