El Ritual, formed in the late 1960s in Tijuana, Mexico, was a pioneering force in the country's psychedelic and progressive rock scene. Founded by Francisco "Frankie" Bareño, the band blended hard rock with jazz and progressive elements, creating a distinctive sound that resonated with the era's countercultural movements. Their self-titled 1971 album showcased this fusion, featuring tracks like "Satanás," known for its experimental and theatrical approach. El Ritual's participation in the historic Avándaro Rock and Wheels Festival in 1971 solidified their place in Mexican rock history. Their legacy endures as a testament to the vibrant and transformative music scene of 1970s Mexico.
