He later joined a jazz and bossa nova trio where he sang and played bass and double bass. José found success as a solo artist in the early 1970s. Demonstrating his vocal ability with a stunning performance of the song "El Triste" in a Latin music festival held in Mexico City in 1970, he climbed the Latin charts during the decade.
