Metallica are close to completing their forthcoming album in LA with producer Rick Rubin. All that is left are the overdubs and James Hetfield's vocals.
The band has compared Rubin's methods to longtime Metallica producer Bob Rock.
Kirk Hammett said: "I have difficulty wading through all the ideas because I'm biased - I think everything we do has a lot of merit to it. In that regard Rick Rubin is great because he will just say, 'Such and such a part is not good, so come up with something else.' He just leaves the problem up to us and we just solve it between ourselves without too much interference from his side."
Hetfield has high hopes for the album: "We don't want pretty good, we want excellent and Rick is getting us to try and achieve that. Rick's very good at getting the essence of an artist out and brining that back to the top again.'"
The new Metallica album is due in the spring.
