John 5's Van Halen connection goes back years as a fan; he then teamed up with David Lee Roth to write and record his 1998 album, "DLR Band." The guitarist has continued to write material with Roth and, last year, revealed that the pair had recorded a second project in early 2013.

"[Dave and I] just made another record, and it's, like, the 'California Sessions', [Dave] was calling it," said John 5. "And it's 11 of the greatest songs you'll ever hear, and it's just me and Dave, and we had Gregg Bissonette play drums on it. And it's unbelievable. And hopefully sometime it'll see the light of day. But he is, of course, busy with Van Halen and all that stuff. But it's an incredible record."

"I always go over to his house and we write music and things like that," he continued. "It's a lot of fun. I would just go over to his house during the day and write this music and then he would book the studio at night. So we would go into A&M Studios - Henson Studios, it's called now - and we'd record."

John 5 described the vibe of the material and Roth's performance. "It sounds just like Dave from that 'Van Halen I' or ' Van Halen II' or 'Women And Children First' era, [in terms of his] singing [style], and it's incredible, man. It's really incredible. He loves it too, so maybe it'll see the light of day sometime."
