Here’s an open letter from Dave Grohl (from the Foo Fighters and Nirvana, maybe you’ve heard of him?), to Metallica urging them not to release new material until it is “kick-ass”.

In the letter Grohl inquires as to whether the band have completed drum parts for their new material – jokingly hinting that he has his eye on a part in the band.

The letter, posted on Blabbermouth, reads:

“Hey, it’s Dave! Remember me? Yeah, I’m the guy that’s been listening to your band faithfully since 1983. I bought your first album ‘Kill ‘Em All’ from a mail order catalogue called Under The Rainbow, I think. Actually I can’t remember. It was 1983 for Christsakes! But that album changed my life and I’ve been listening to your albums ever since (even ‘St Anger’!).

“I can’t wait to hear the new shit, and no matter what you guys do I’ll always be first one at the shop waiting to hear it. I’m sure you’ll come out and blow everybody’s fuckin’ minds, because you’re fuckin’ METALLICA!

“Good luck. And don’t release it until it’s kick-ass.

“Yours, Dave Grohl.

“P.S. Are you finished recording the drums yet?”
