(CNN) -- Today is the 56th anniversary of "the day the music died."
On this day in 1959, rock and roll legend Buddy Holly was killed when his plane slammed into an Iowa cornfield in a blinding snow storm.
Teen idol Ritchie Valens and disc jockey "The Big Bopper" died with him.
They were in the middle of the Winter Dance Party tour, flying to their next date in Minnesota. The plane crashed just minutes after takeoff.
No one is exactly sure what went wrong.
Don McLean immortalized the tragedy in his song "American Pie."
Holly was only 22 years old.
