The Rock and Roll Hall of Fame Foundation is delighted to announce their 25th Anniversary this coming year. Leaders in the music industry joined together in 1983 to establish the Rock and Roll Hall of Fame Foundation. One of the Foundation's many functions is to recognize the contributions of those who have had a significant impact on the evolution, development and perpetuation of rock and roll by inducting them into the Rock And Roll Hall of Fame.

In honor of our 25th Anniversary, each night will highlight different artists that will not only celebrate their music, but invite musical guests to join them onstage for what will be two unforgettable evenings with unique collaborations.

"Twenty-five years ago a group led by legendary Atlantic Records founder Ahmet Ertegun created this foundation to recognize and celebrate the music and careers of artists whose music helped shape and define our generation," said Jann Wenner, Founder and Chairman of Rolling Stone and Chairman of the Rock And Roll Hall Of Fame Foundation. "These once-in-a-lifetime concerts are designed to celebrate the artists and their music."

A creative team of Tom Hanks and his producing partner Gary Goetzman, Wenner, singer-songwriter ROBBIE ROBERTSON, Academy Award-winning screenwriter, director Cameron Crowe and several others will work with the artists to curate the show through the live performances and filmed segments. Joel Gallen, the producer/director behind the Rock and Roll Hall of Fame induction ceremonies and the MTV Movie Awards (1995-2006), will direct the show and oversee the 25th anniversary celebration along with the creative consultants.
