Ritchie Valens made the Mexican folk song La Bamba world-famous in 1958, even though it was just the B-side of the single Donna. La Bamba is an example of Chicano Rock, rock music with Latin-American influences. Ritchie Valens could not enjoy his celebrity for long, in 1959 he was killed in an air accident, together with Buddy Holly and his band.
