After this weekend's Big Four spectacle in Indio, CA, Metallica's Lars Ulrich says more concerts with thrash icons Slayer, Megadeth, and Anthrax are in the works. The bands are looking into booking dates across the country, although there are no plans to turn it into a touring festival. "I like the fact that there's an element of chaos to the whole thing, " Ulrich said. "It shouldn't be sterile, streamlined, and perfect: it needs an edgy underbelly to remain authentic." No dates have been announced yet. \t At the final performance of Green Day's Broadway production of American Idiot, the group surprised attendees by delivering an improptu set of Green Day songs.

"Royce and I started hanging out again and inevitably that led us back into the studio," Eminem said in a statement. "At first we were just seeing where it went without any goal in mind, but the songs started to come together, so here we are." \t Kate Bush has teamed up with British actor Robbie Coltrane to star in a video for a reworked version of her 1989 song "Deeper Understanding."
