Buddy Holly (born Charles Hardin Holley; September 7, 1936 â February 3, 1959) was an American musician and singer-songwriter who was a central figure of mid-1950s rock and roll. Holly was born in Lubbock, Texas, to a musical family during the Great Depression; he learned to play guitar and to sing alongside his siblings.
The Day the Music Died. The Day the Music Died. February 3, 1959. On a cold winterâs night a small private plane took off from Clear Lake, Iowa bound for Fargo, N.D. It never made its destination. When that plane crashed, it claimed the lives of Buddy Holly, Ritchie Valens, J.P. âBig Bopperâ Richardson and the pilot, Roger Peterson. Three of Rock and Rollâs most promising performers were gone. As Don McLean wrote in his classic music parable, American Pie, (annotated) it was âthe day the music died.â.
