NBC is gearing up to celebrate the music of Elvis Presley with Sunday’s “Elvis All-Star Tribute” hosted by Blake Shelton and featuring music superstars of today performing some of the rock icon's most beloved songs.

The two-hour event is a tribute to the rock icon's legendary '68 Comeback Special that originally aired on NBC.

But here in Cleveland, we’re always paying tribute to Rock and Roll, thanks in no small part to the Rock & Roll Hall of Fame and Museum. But what you don’t get to see when you visit the museum is the private “vault” where curators keep precious rock artifacts that aren’t on display. The vault is usually only open to very select Rock Hall staffers and A-List visiting artists, but WKYC’s Betsy Kling was lucky enough to get an invite inside.

After entering the secure, climate controlled room, Betsy and Curator Amanda Pecsenye got an up close and personal look at items once worn or owned by music superstars (and Rock Hall Inductees) like The King himself, Prince and Eric Clapton. And as Betsy learned, the vault is also home to items from artists who haven’t yet been inducted – like Beyonce.

The vault itself may not be as glamorous as some of the museum’s exhibits, but the team takes great care in making sure these artifacts remain in the best possible condition.

“We’re the number 1 collection of rock and roll artifacts in the world and we really want to preserve them for many, many future generations to come.” Said Pecsenye.
