Robert Plant is bringing his Sensational Space Shifters to this year's Lockn' Festival for a pair of very unusual headlining sets.

According to a press release, Plant's appearances are scheduled for Sept. 12 and 13, and will find him delivering "two completely different sets" over the two-night span. "Plant has never done anything like this in his career," adds the announcement, "and it will undoubtedly make for some unique and historical moments."

This year's Lockn' Festival will take place Sept. 10-13 at the Oak Ridge Farm in Arrington, Va., and features a bill that also boasts appearances from Phil Lesh & Friends with Carlos Santana, Jorma Oaukonen and Jack Casady celebrating the 50th anniversary of Jefferson Airplane, Gov't Mule, Little Feat, the Doobie Brothers with the String Cheese Incident and an exclusive performance of Mad Dogs & Englishmen featuring Tedeschi Trucks Band, Leon Russell and other special guests.

Tickets for the festival are on sale now, with a four-day general admission pass going for $285. For more information about Lockn' Fest or to order tickets, visit the official event site.

Plant's stop in Virginia will come toward the end of a crowded summer and fall touring schedule that's seen him traveling the world in support of his most recent studio LP, lullaby ... and the Ceaseless Roar. In addition to his official calendar, he's been making sporadic unannounced appearances, including a recent surprise visit to the Ludlow Fringe Festival in early July.
