Watch VAN HALEN's DAVID LEE ROTH Perform 'Jump' With Dutch Producer ARMIN VAN BUUREN

VAN HALEN singer David Lee Roth made a surprise appearance during Dutch producer Armin Van Buuren's headlining set at the Ultra Music Festival Saturday night (March 30) in Miami, where the duo performed a remix of the band's biggest hit, "Jump".

Armin told Rolling Stone that the remix came together when a friend of his offered to send him the song's recording stems. "I'm like, 'Yeah, hell yeah,'" the producer said. "I knew the song already as a kid. I think I was 6 years old when the track was a No. 1 hit everywhere. I was just eager to have the stems, because I always thought, 'What if you could have the energy of that song from 1982 and transfer it to 2019?'" He sent it to Roth a few weeks ago, and the singer loved it.

"Just the fact that David is open for such a thing is quite huge to me," Van Buuren said.

"I agree with all of that," Roth added. "It's the first step toward world peace if we can do it."

Asked if there are any other songs from his catalog that he would want to remix, Roth said: "They're all eminently remixable, but there are so many different genres of 'the groove.' And whether it's dubstep, chill, trance and on and on, and yeah, judge, I admit it. I knows the difference.

"If you're talking remix, I'm an extremist, and I would head for Korea. We're in Henson Studios in the heart of Tinseltown. Pharrell is walking these halls and John Mayer is recording and rehearsing across the hallway; he lives here now in the studio. THE GRATEFUL DEAD's been very, very good to him. God bless them. But no, there's a whole lot of Shakespeare going on here, musically and theatrically. And when you say, 'remix,' that could be 15 different haircuts before happy hour. Yes, yes, yes. You want me to say it 15 times?"

Roth's collaboration with Van Buuren comes weeks after a recent rumor suggested that the original VAN HALEN lineup — including bassist Michael Anthony, who has not played with the band since 2004 — would reunite in 2019 for a run of stadium shows. This would be the first time that the four founding members of the band, including Roth, guitarist Eddie Van Halen and drummer Alex Van Halen, perform together since 1984.

VAN HALEN has been inactive since it completed its U.S. tour in October 2015 at the Hollywood Bowl in Los Angeles, California.

The trek was VAN HALEN's first since an aborted North American run three years earlier in support of its then-new studio album, "A Different Kind Of Truth".

Roth recently launched Ink The Original, a skin-care line specifically made to preserve, protect, and highlight tattoos and keep them from fading.
