Metallica rocker Lars Ulrich is offering up a private drumming lesson to one lucky fan as part of an all-star charity auction run by former tennis champion Andre Agassi.
The Danish musician has donated the prize - which also includes flights, accommodation and a tour of the band's studios - for the top bidder and a guest at the Andre Agassi Foundation for Education's upcoming fundraiser.
The auction, which raises money for disadvantaged youths, also features the chance to win a dinner party with funnyman Robin Williams.
Sir Elton John and Jason Mraz will perform at the event, which takes place in Las Vegas on 9 October (10).
