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.
When he died, he was only 22. On February 2, 1959, Holly and his tourmates were on the eleventh night of their Winter Dance Party tour through the snow-covered Midwest. It was a Monday â a school night â but 1,100 teenagers crammed into Clear Lake, Iowa's Surf Ballroom for two sold out shows.
