Rock en español es la música rock compuesta e interpretada en castellano. A diferencia del rock en inglés, el rock en español ha logrado tener éxito mundial en pocas ocasiones, y muchas veces ni siquiera entre países de habla hispana. Por eso el rock en castellano se ha desarrollado de manera heterogénea en las distintas naciones hispanohablantes; quedando así la música de muchas bandas para uso casi exclusivamente nacional hasta la llegada de la globalización de contenidos multimedia acentuada por la generalización de internet y desarrollada especialmente en el siglo XXI.
A los 15 años, Joan formó The Runaways con otras tres rapadas, Sandy West, Lita Ford y Cherie Currie. Joan cantaba, tocaba la guitarra rítmica y escribía mucho material de la banda. La banda grabó cinco LPs y giró por todo el mundo entero junto con Cheap Trick, Van Halen, Tom Petty y The Heartbreakers. Tuvieron especialmente éxito en Japón.
Mientras que The Runaways eran muy populares en Europa, Japón, Australia, Canadá y en Sudamérica, ellas no tuvieron el mismo éxito en Estados Unidos. Parte de eso se debió a que en este país la prensa musical no estaba acostumbrada a que una banda de mujeres adolescentes harían música con seriedad. The Runaways se separó en 1979.
