Professionally filmed, high definition footage of Hellyeah's May 27th performance at the Rocklahoma festival was posted online Tuesday, and can be seen below.  The festival gig came with a surprise for Hellyeah fans who made the trip to Pryor, Oklahoma, as guitarist Greg Tribbett showed up for the gig despite sitting out a couple of other shows due to a family emergency.

Hellyeah is a thrash metal supergroup consisting of former Pantera drummer Vinnie Paul, Mudvayne frontman Chad Gray and guitarist Tribbett, Nothingface guitarist Tom Maxwell and Damageplan bassist Bob Zila.  The band will release its third album, "Band of Brothers,"  on July 17th on Eleven Seven Music.
