Van Halen is working on its 13th studio album, according to Alter Bridge guitarist Mark Tremonti. Blabbermouth reports that Tremonti -- whose bass player in his solo band, Wolfgang Van Halen, is also the bassist in Van Halen -- spilled the news in an interview with VH1, saying, "With Wolfgang in the band now, he does a lot of work with Van Halen right now, they're putting together a new album, so it's going to be hard to get everybody's schedules to line up."

Tremonti admitted, however, that Wolfgang has not told him much about the next Van Halen effort, saying, "You know, he doesn't. He just says, 'Yeah, sounds great, man. Sounds great.'"

The question, however, is whether the material will be freshly written or pulled from the band's vaults.

Many of the songs on 2012's A Different Kind Of Truth originated from demos going back to the group's earliest days, with Wolfgang telling us, "There's plenty of other ideas lying around."

Singer David Lee Roth said in an interview late last year that Van Halen had started work on a new record, revealing, "I write lyrics routinely and the band plays together routinely, at least three times a week up at Ed (Van Halen)'s place."
