Hermética

Hermética was an Argentine thrash metal and heavy metal band from San Martín, Buenos Aires. It was formed by bassist Ricardo Iorio in 1987 after his previous band, V8, disbanded. Hermética was signed to independent record label Radio Trípoli Discos throughout their career. The band's initial lineup consisted of Iorio, vocalist Claudio O'Connor, drummer Fabián Spataro and guitarist Antonio Romano. Spataro left the band in 1988 and was replaced with Antonio Scotto. This lineup recorded their eponymous album, the first thrash metal album recorded in Argentina. At that point, Hermética performed mainly in Argentina, except for one concert in Uruguay. In 1990, they released the EP Intérpretes, which included covers of Argentine rock and tango songs. Both albums were released by Radio Trípoli Discos as a single CD when digital technology became available.

Scotto left the band in 1991 and was replaced with drummer Claudio Strunz. This lineup recorded the band's second studio album, Ácido Argentino. Hermética opened for Black Sabbath and Motörhead during their visits to Argentina, but cancelled their headlining tour of Paraguay. They recorded the live album En vivo 1993 Argentina, and played at a penal facility. They participated in the first Argentine Monsters of Rock festival, which featured Black Sabbath, Slayer, and Kiss. Their last studio album, Víctimas del Vaciamiento, was released in 1994. To promote the album, the group performed at the Obras Sanitarias stadium later that year.

Hermética disbanded at the end of 1994, a few days before their second concert in Obras. Ricardo Iorio, who performed lead vocals on a number of tracks, formed a new band, Almafuerte, and served as its vocalist. The remaining ex-members of Hermética hired a new bassist and created the band Malón. Both bands began a rivalry.
