This year’s Grammy Awards collaboration between Metallica and Lady Gaga was a very controversial one, but the gruesome twosome aren’t finished yet.

In an exclusive interview with Metallica’s bassist Robert Trujillo, the former Ozzy Osbourne and Sucidal Tendencies player explained that although they are currently touring in support of their latest album Hardwired to Self Destruct, the band has already written their next album, which will feature Gaga as a second vocalist on each track as well as playing piano on certain tracks.

“When James’ mic went out at the Grammy’s she (Gaga) took the reigns and absolutely knocked it out of the park,” Trujillo said. “We realized we had something special and decided to take it to the next level.”

The album will also feature many more guest appearances on each track and will include previously archived sound clips of Lou Reed and Cliff Burton.

The untitled album is scheduled to be released sometime in the fall and will come with a bonus disc featuring the band (with Gaga) covering songs from the latest Diamond Head album (self titled) as well as other favorites from both camps. Both tracklists with their working titles and the full list of covers can be viewed below.

“We’re all stoaked for this to come out and it was really awesome to work with her,” said Trujillo. “It’s something wicked that both ‘Tallica fans and Gaga fans are really going to appreciate.”
