Trio Galleta was a soul rock band formed in 1969 in Mar del Plata, Argentina.

In 1970, when the trend of singing in English language in Latin America had little acceptance, they released their first album made only of cover versions called Estoy Herido through Odeon Records, with the track list ranging from "Río Verde" ("Green River") by Creedence Clearwater Revival to "Enciende mi Fuego" ("Light My Fire") by The Doors, under the genre that would become known as soul rock.

Their influences on this album were Otis Redding, James Brown, Ray Charles, Stax, Wilson Pickett, Johnnie Taylor, Motown, Jeff Beck Group, Bill Deal and the Rhondels, Steve Cropper, Creedence Clearwater Revival, Southern Soul and Small Faces.

On the back cover of the album was written that their lyrics ranged from subjects concerning LSD to racial issues.

As a final attempt, in 1975 Iturbide decided to continue the project and reformulated the band's line-up, now a quartet, to include Eduardo Sanz, as a guitarist, Lito Olmos, on bass, and Maria José, on drums.
