Back in February it was revealed that Metallica bassist Robert Trujillo was collaborating with Torche drummer Rick Smith on a new project. Today (July 23), we learned a bit more about the other members of the one-off group, and that it will benefit the Tony Hawk Foundation.

Noisey spoke with Brent Eyestone of Harmonic Cross, who said the other members are his bandmate Graham Scala and Nate Newton from Converge. "We're doing this record," he said. "It's just going to be a couple of tracks that we're going to put it out digitally and on vinyl.

As for the money it brings in, Eyestone said that it's going to a cause that is close to Trujillo's heart. "We all like to skate and we believe in that charity; making free skateparks for lower-income areas," he continued. "There's no name and no release date, but once it's done all proceeds will go to public skateparks."

Still, they're not really sure what shape it's going to take. "We're just rabid musicians who want to make new stuff and not put a cap on what it is," he said. "It could be an ambient record, it could be a weird, negative hardcore record, or just a band with people we didn't think we could get."

The downside of this for Metallica fans is that it's one more project that could potentially be preventing the completion of their next album. Back in April, Kirk Hammett said that the long-awaited follow-up to 2008's Death Magnetic was "at the 25 percent point, maybe 30 percent point."
