Saw all these guys perform yesterday at Dubai's Desert Rock Fest. Sepultura was very very tight. Loved Igor's drumming, what a machine! The new vocalist (Derek is it?) was really good, great stage presence. He was such a beast on stage, really got the crowd growing. They played all the classics aswell as new stuff. Machinehead were also awesome, very heavy set...Old, Imperium, Davidian, Bulldozer, Creeping Death by Metallica! They had Andreas from Sepultura on stage to pull off the Metallica cover. great stuff. Darkness were really entertaining, heard alot of their new material and its sounding very cool. Justin was lifted on a bouncer's shoulders and walked around the crowd as he solo'd...He was using a wireless system. What a rock star. Dont know the names of any of the bassists of any of the bands, but they were tight. Went to the gig more just to jump around and let loose. Anyone else seen these guys recently?
