Mayhem Fest hit Dallas, Texas on Wednesday, August 10th and those in attendance were treated to a fitting tribute to Dallas, Texas' own legend "Dimebag" Darrell Abbott.

Disturbed was joined onstage by several members from Godsmack, Trivium and All Shall Perish to rock out an amazing version of "Walk." 

I was privileged to see Disturbed perform "Walk" with Dimebag and Vinnie Paul at Ozzfest back in 2003 at the Smirnoff.  That was just over one year from when Dimebag would be slain onstage during a Damageplan show in Columbus, Ohio.

After doing a little digging I was able to find videos from both perfomances
