Rock en Español (Spanish for Rock in Spanish) refers to the Spanish-language rock music. Latin rock is a fusion of the rock music with the latin American rhythms an – also – with some instruments which are typical for this music like percussion, but also piano riffs known from son cubano or merengue. Successful musicians and groups playing in this genre are often noted for being "cross-over" artists, as this genre inherently bridges both linguistic and cultural categories.
