Mazza is expected at an awards ceremony today - but first he checks out Queens Of The Stone Age...
According to eyewitness reports, Manson watched the gig from the right-hand side of the stage. Other artists in attendance included The Dandy Warhols and Dukes Of Nothing.
Playing in front of a sold-out crowd, Queens played a varied set, including old Kyuss tracks and some by Nick Oliveri’s side project Cocaine Rodeo.
Manson is also expected to turn up at UK metal magazine Kerrang!’s awards, which are being held today (August 29) at the London Hammersmith Palais.
Check back later on nme.com for a full report of the Kerrang! awards – the winners, the losers and the full low-down on the debauchery that’s bound to ensue.
