Jonathan Davis was rushed to hospital. Similar to 2004's Metallica set, Munky, Fieldy and David Silveria arrived and explained to the fans why Davis could not make it and played with guest vocalists Corey Taylor from Slipknot, Dez Fafara from DevilDriver, Jesse Hasek from 10 Years, Benji Webbe from Skindred, M. Shadows from Avenged Sevenfold, and Matt Heafy from Trivium. Lyrics from the song "Blind" were displayed on the screen for Matt Heafy. Metallica played the album Master of Puppets in its entirety in honour of its twentieth anniversary. Guns N' Roses also performed material from the long forthcoming Chinese Democracy album. Main Stage The main stage was situated in the centre of the arena with crowd control moving around it, and was the largest of all three stages, the safety barriers used at this stage were in a T shape so as to avoid crowd crush in the middle. The stage was open-air and named in honour of the 25th anniversary of Kerrang! magazine. Down played an unannounced set on Saturday (With the laminates showing ??? in their time slot); opening up the Main Stage. Snickers Stage The Snickers Stage was situated in a tent, behind the main stage and was the second largest stage at the festival. Access to the stage was via a one-way system which attempted to spread people around the site, rather than all attempting to push through a rather small space. Soilwork were scheduled to play on Sunday, but were replaced by DevilDriver (playing their second set of the festival). Gibson/Myspace Stage The Myspace stage was the smallest of the three and under a smaller tent. It was positioned across from the front of the main stage. Controversy During the Sunday headline set of Guns N' Roses, bottles were thrown at the band. This caused problems after the band's lead singer, Axl Rose, slipped on the wet surface and a bottle hit bassist Tommy Stinson. Stinson threw his bass, hitting one of the cameramen, and left the stage. He returned after the song and apologised, but warned the crowd that if this activity continued, he would leave for good. There were some disturbances but they eventually died down, and later in the set Rose commented "I'm actually having quite a good time now! I couldn't have said that an hour ago!" On the final night, fires were started by some festival goers and police
