Gene Simmons rocked and rolled all day in Cleveland Saturday, making good on a promise to his fans.
The Kiss front man stopped by the Rock and Roll Hall of Fame to hand-deliver a box set of his greatest hits and unreleased music, and dozens of fans lined up to get their hands on one.
Gene tells us it weighs more than 40 pounds and features more than 10 hours of music never released to the public, including collaborations with greats like Bob Dylan and Joe Perry.
While it was obviously a great experience for the fans, Simmons says it's been on his bucket list, as well.
