Featured with ZZ Top are Lynyrd Skynyrd, Jamey Johnson and Corey Taylor. Skynyrd and ZZ Top have a relationship that dates back to the early 1970s and they have worked together extensively ever since. They've most recently shared concert bills on the Rebels & Bandoleros Tour.

Jamey Johnson is one of the key contributors to the just-released A Tribute From Friends, the album of ZZ Top cover songs by a slew of the band's admirers including Nickelback, Grace Potter, Daughtry, Wolfmother and The M.O.B. (Mick Fleetwood, Steven Tyler, Johnny Land and John McVie) and others. His contribution to the collection is, appropriately, "La Grange" with none other than ZZ ax man Billy Gibbons guesting on the track that's the album's closer.

Corey Taylor is a recent addition to La Grange Fest's line up and he'll be performing an acoustic set on Saturday. Taylor is the multiplatinum selling, New York Times best-selling author and Grammy® Awardwinning singer/ songwriter in Slipknot and Stone Sour, two of the most successful bands in rock music today. There's a distinct possibility that he'll be joining ZZ Top for a song or two.
