On June 16th, 1972 a folk-rock all acoustic event called Acusticazo took place at the Teatro Atlantic. Gabriela, Litto Nebbia, Miguel y Eugenio, Leon Gieco and a young singer Raúl Porchetto played on that event. Raúl's performance of "Cortar el viento" was included on the album. For his first LP, a conceptual opus called Cristo Rock (Christ Rock), he was joined by Charly García (keyboards) and Oscar Moro (drums), along with the usual La Pesada staff: Billy Bond (mixing console and effects), Claudio Gabis, Kubero Diaz (guitars), Alejandro Medina (bass), Jorge Pinchevsky (violin) and Jimmy Marquez (drums). A string orchestra and a church organ were also used for the recording. Cristo Rock has an "Obertura" and eight numbered tracks. It is a strange but attractive album, full of climatic sounds and interesting playing; more noteworthy Gabis' wah-wah guitar.
