The production, created by Rob Evan and Randall Craig Fleischer, mixes hits by Elton John, Queen, Journey, Led Zeppelin and The Who with pieces by legendary classical composers.

During Tuesday’s preview, reporters heard Elton John’s “Don’t Let the Sun Go Down on Me” as a mash-up with a piece by Handel; Heart’s “Alone” mixed with Rachmaninoff; Patti Smith Group’s “Because the Night” melded with Tchaikovsky, and Zeppelin’s “Kashmir” blended with Puccini’s “Nessun Dorma.”

Is Rocktopia for rock fans or classical buffs? “It’s for both, for sure,” Fleischer tells ABC Radio. “We’re both classically-trained musicians. Rob’s career is more…pop, my career is more..classical, but since we wrote this, and we love both, this is really a show for anybody.”

The show starts a six-week run March 20 at The Broadway Theatre; tickets are on sale now. The first three weeks feature a guest vocalist — Train frontman Pat Monahan — with more to come.

Explaining the guest concept, Evan says, “Randy and I agreed a long time ago that we were never going to do a gimmick. We wanted to make it about the vision and about what we’re doing. But we need to sell tickets.”

Evan and Fleischer say rockers who want in must be fully committed to the concept, and they say there’s no shortage of interested parties.

“We have a lot of people that are gonna jump in that I can’t tell you about right now,” Evan teased. “The top of the top of the icons are looking at us right now…so I don’t wanna talk about it. I don’t wanna jinx it!”
