Drive-By Trucks have been added to the bill for this year’s Lockn’ Festival. The Southern rockers join a lineup that already includes The Allman Brothers Band, Phil Lesh & Friends, Bob Weir & RatDog, Widespread Panic, The String Cheese Incident, Wilco, Willie Nelson, Gary Clark Jr., Grace Potter & the Nocturnals and Chris Robinson Brotherhood. Many of the above artists are slated to perform on multiple nights, and Widespread Panic will be joined by Steve Winwood during one of their sets.

Lockn’ has also added a number of other artists in recent weeks, including Umphrey’s McGee, Keller Williams’ Grateful Gospel and Grateful Grass, Preservation Hall Jazz Band, The Wood Brothers and Hot Tuna Acoustic. Another artist is expected to be announced tomorrow.

Lockn’ will return to Arrington, VA on September 4-7. General Admission tickets as well as a variety of VIP packages are now on sale.
