Ritchie Valens. In an all too brief career, Ritchie Valens was the first Chicano rock and roll star, having his best remembered hit, La Bamba, just one month before his untimely death with Buddy Holly and the Big Bopper on February 3, 1959.
Various re-workings and compilation albums have appeared in the years since. Holly was commemorated in the musical Buddy which opened in London in 1986. Mexican American group Los Lobos achieved a hit with La Bamba when they collaborated on the 1987 film of the same name, a biography of Ritchie Valens. Buddy Holly and, to a lesser extent, Ritchie Valens became musical legends.
