Rock veterans Metallica have rubbished rumours they plan to sack longterm producer Bob Rock and hire Rick Rubin to make their new album.

Drummer Lars Ulrich insists Rock with be in the driving seat when the band hits the studio for the follow up to last LP ST ANGER, and they've never even thought about replacing him.

Ulrich says, "I would say that Bob Rock will always be our producer. You know, it's almost like default. It's not whether he should produce, it's more whether he shouldn't produce it."
