Manal is an iconic rock band from Argentina that played a fundamental role in the history of Spanish-language rock and roll. Its primary lineup consisted of Javier Martínez on drums and vocals, Alejandro Medina on bass guitar, and Claudio Gabis on lead guitar. Formed in the late 1960s, the band’s music was characterized by a potent blend of blues, jazz, and rock, laying down the framework for rock nacional, the Argentinian rock movement. Manal was renowned for their innovative sound, integrating complex musicianship with lyrics that reflected the social issues and urban life of Buenos Aires.

Though their initial run was short-lived, Manal's impact on the music scene was profound. After disbanding in 1971, they left behind a legacy that influenced countless Latin rock musicians. The group briefly reunited in 1980 for a notable live performance, documented in the album "En Obras 1980 (En Vivo)," which captured the raw energy and uniqueness of their stage presence. Over time, Manal's work like "El León" came to be revered as classic rock staples in Argentina, and compilations such as "Obras Cumbres" and "Colección Rock Nacional - El León" serve as enduring testaments to their contribution to the genre. They are remembered today not only for their groundbreaking work but also for their reunion efforts, allowing new generations to experience their powerful and influential music through albums like "Reunión".
