Mexican el Tri started playing in the late '60s under the name of Three Souls in My Mind, singing in the English language until they released their third album. The band, led by Alejandro Lora, has been considered a Latin rock pioneer. In 1971, Three Souls in My Mind joined the Avándano Festival, known as the Mexican Woodstock, playing in front of their largest audience ever. El Tri achieved a gold record after releasing Simplemente el Tri in 1985 which featured the hit singles "Triste Canción de Amor" and "Vicioso del Rocanrol." The group toured the U.S. after participating in a Hispanic rock festival in Madrid. El Tri's discography includes three successful live albums recorded in Santa Martha, Hollywood's Palladium, and Mexico City. The group achieved an award from the Mexican Cinematographic Academy for their contribution to the local movie Un Año Perdido. Grammy-nominated Cuando Tú No Estas followed in 1998. On October 12, 1968, Three Souls in My Mind performed live for the first time. To celebrate their 33rd anniversary, Sinfónico, Vol. 2 was released. In addition, a festival called El Tri-Fest was held at Mountain View's Shoreline Amphitheater. ~ Drago Bonacich, Rovi
