This year marks the 56th anniversary of the tragic plane crash that claimed the lives of Buddy Holly, Ritchie Valens and JP "The Big Bopper" Richardson, Jr.

Visitors to the Lubbock's Buddy Holly Center, which opened its doors free of charge on Tuesday, Feb. 3 (commonly known as The Day The Music Died), took in the history of not just a man, but a force that shaped music for decades.

On display are trinkets from Holly's boyhood, including drawings and clay moldings; letters addressed to the singer; musical instruments he wrote music on; and, nestled away in a small glass case, Holly's iconic glasses.

Not just any pair, but the singer's glasses recovered after the fateful 1959 crash that cut his life short.

Just as impressive as the artifacts displayed inside the Buddy Holly Center's museum is the J.I. Allison House.

It was inside this home, which was originally located at 2215 6th Street in Lubbock, that Holly and original The Crickets member J.I. Allison wrote the song "That'll Be the Day" in 1956.
