Megadeth's Dave Mustaine is continuing his campaign for 'Megatallica' or 'Metallideth' despite the fact that Metallica's James Hetfield and Lars Ulrich have turned down the offer to join forces.A couple of weeks back it was revealed that Dave Mustaine approached the two elder statesmen of Metallica in hopes that they would join himself and Megadeth bassist David Ellefson in a supergroup. Though James reportedly said no, Mustaine remains optimistic that the project may happen.

In light of their recent collaboration with Lou Reed, The Boston Phoenix asked for his thoughts on working with his former bandmates from Metallica:

"Well, I already did a project with Metallica a long time ago. You mean another project with Metallica? I dunno. . . . If they're digging up old guys to rock with, those guys are a little bit older than I am, I may have to have my AARP card to do it [laughs]. No, of course I would do it — that was my band. Megadeth was what the next logical step was in my musical career. It was a natural progression, but if an opportunity came for us to play again — I think that would be ideal, and I've talked to James about this before. And he didn't say "No," that he and I and Lars and [Megadeth bassist] David Ellefson should do a record together and see what happens. Not as a band or anything like that, but something to donate the money to charity. We're all getting a lot older now and just the fact that we're talking was a great start. Playing together is even better, and the idea of us doing something together could be just too much for my little brain to handle and it might just explode.

It may be unclear whether the two thrash metal heavyweights will share a studio anytime soon, they will be sharing a stage when The Big 4 comes to New York's Yankee Stadium September 14th."

Though the two bands have made peace of late, it appears they still are competitive with one another. Metallica announced that their collaboration with Lou Reed titled 'Lulu' will be released the same day as Megadeth's 'TH1RT3EEN' -- November 1st.
