 Hermética made regular appearances at the Arlequines theater in San Telmo in 1989. They were the first heavy metal band to play there. They performed with the bands Doppler, 666, Militia, Genocidio, Ultraje, Cross, Legión, and Devastación. Hermética wanted to record their first album but the national economic crisis had a negative impact on the project. The fanzine "Rebellion Rock" proposed an independent production, which would be sold at Parque Centenario, but the band rejected this offer. They also rejected working for EMI and instead signed for a new label, Radio Trípoli Discos. They signed a contract in May 1989, and two months later the band began to record the LP at the Sonovisión studios. The eponymous album Hermética was released in November 1989. It was the first thrash metal album to be recorded in Argentina. Ricardo Iorio made his debut as lead vocalist on the song "Desde el Oeste". Hermética performed a concert in Córdoba, with the band Hammer. Alberto Zamarbide, a former singer with V8, made a guest appearance during a concert in Mataderos. Hermética ended the year by performing two concerts with Pappo's new band Pappo & The Widowmakers.
