Café Tacvba (pronounced Café Tacuba) is a band from Naucalpan, Mexico. The group is widely credited with being a pioneering group of the Rock en Español movement, which gained popularity in the early 1990s. They were founded in 1989, and since then have had the same musical lineup of Rubén Isaac Albarrán Ortega (vocals, guitar), Emmanuel "Meme" del Real Díaz (keyboards, guitar, piano, programming, vocals, melodica), José Alfredo "Joselo" Rangel Arroyo (guitar, vocals), and Enrique 'Quique' Rangel Arroyo: (bass guitar, electric upright bass, vocals). Mexican folk music player Alejandro Flores is considered the 5th tacuba, as he has played the violin in almost every Café Tacuba concert since 1994. Since the Cuatro Caminos World Tour, Luis "El Children" Ledezma has played the drums in every concert but is not considered an official member of the band.
