Conspiracy theorists, rest easy.

The Rock and Roll Hall of Fame is just fine. In fact, Rock Hall chief executive Greg Harris says 2016 was one of the best years ever for the museum in Cleveland, buoyed by a double-digit attendance increase and a major renovation.

So the idea that the sudden influx of popular ’70s bands like this year’s inductees Journey, Electric Light Orchestra and Yes — fan favorites who have long been eligible and yet passed over — is some sort of ploy to save a struggling museum is wholly misguided. The simpler explanation: A lot of people like those bands — as well as recent inductees Kiss, Chicago and Rush — and more and more of them are Rock Hall voters.

“The single biggest voting body for us — 600-plus voters — is all the other living inductees, and their demographics are changing,” Harris says. “Great songwriting and great performances do endure, and there’s a period where eventually that gets recognized.”

That’s not to say Hall of Fame voters are ignoring other styles of music. Grunge heroes Pearl Jam and rapper Tupac Shakur will each be inducted in their first year of eligibility, 25 years after the release of their debut albums in 1991.

“It’s a phenomenal class,” Harris says, adding that many people are surprised that folk legend Joan Baez wasn’t already inducted. “It’s really neat to see all the different strains under the big tent that we call rock and roll represented.”

Besides the induction ceremony Friday night at Barclays Center, Lenny Kravitz will pay tribute to Prince. HBO will air an edited version of the ceremony at 8 p.m. April 29.
