My love of Slipknot is well known and news that they guys got it together to play this festival is very good news. More after the jump.

You can see in the video that they guys wore their "old school" uniforms for the show. What you can't see is that on stage was Paul Gray's Uniform and mask. The fill-in bass player played from behind a screen. The guys are obviously charged and rocking, which is good news (I saw some of System of a Downs "return" shows and they seem very unexcited to be back together). There are conflicting reports on whether the guys will make a Slipknot Album or Stone Sour album next.

Enjoy this fan shot footage of "Duality" live. The sound is better on the second one, but the first one features a better intro and a little glimpse of the display of Paul's stuff.
