His professional musical career began in 1967 when he was sixteen years old and founded the group Arco Iris, an Argentine band that amalgamated rock and traditional Latin American music in cooperation with 'national rock'. The band was also part of a yoga community led by Danais Wynnycka (named Dana) and his partner Ara Tokatlian. Gustavo wanted to escape the strict requirements of Dana (which forbids meat, alcohol, drugs, and especially sex) and left the group in 1975.
A year later, he formed Soluna, where he played with pianist and singer Alejandro Lerner and his girlfriend (at the time) Monica Campins. Together they recorded only one album (Energía Natural, with Charly García, Mauricio Veber and Rody Ziliani as guests 1977). Santaolalla then went to Los Angeles, where he adopted a rock and roll sound and also played with his band Wet Picnic (with a former member of Crucis, Anibal Kerpel).
