José Fernando Arbex Miró (28 May 1941 – 5 July 2003) was a prominent Spanish musician and songwriter from Madrid. He began his musical career as a drummer with Los Estudiantes, a pioneering pop-rock band in Spain. In 1965, Arbex co-founded Los Brincos, a highly successful pop band often referred to as the "Spanish Beatles." Following the dissolution of Los Brincos in the late 1960s, he formed the progressive rock trio Alacrán with Iñaki Egaña and Oscar Lasprilla. After Lasprilla's departure, Arbex and Egaña established Barrabás, a Latin disco and rock-oriented band that achieved significant success in Europe and the United States, particularly with their hit single "Woman."

Beyond performing, Arbex was a prolific producer and songwriter, collaborating with renowned artists such as José Feliciano, Harry Belafonte, Nana Mouskouri, Emilio Aragón, Miguel Bosé, and Middle of the Road. His compositional talents extended to the realms of cinema, ballet, and musical theater, notably contributing to the first Spanish musical "La Maja de Goya."

In 2000, Arbex reunited Los Brincos for a successful concert in A Coruña and recorded with a reformed Barrabás. He passed away in Madrid on 5 July 2003 after a long illness, leaving behind a legacy as a versatile and influential figure in Spanish music.
