Santaolalla’s first major musical vehicle, Arco Iris, helped forge Argentina’s rock nacional, but its internal life was far from ordinary. Formed in 1967, the band lived communally and embraced a quasi‑spiritual regimen—celibacy, vegetarianism, abstention from alcohol and drugs, and immersion in Eastern religious ideas—led in part by their vocalist and spiritual guide, Danais Winnycka. While Arco Iris produced several influential albums (including the breakout single “Mañana campestre”), cracks appeared as members questioned how inwardly directed the group had become. Santaolalla later described the group’s dynamic as running the risk “of turning into a cult.” Conflict with wind instrumentalist Ara Tokatlian and mounting concerns about oppressive communal control culminated in an extraordinary family intervention: Santaolalla called his mother, who organized an operation to “rescue” him from the group. He left Arco Iris and went on to form the hard rock group Soluna. The story underscores an odd chapter in Latin rock history where countercultural idealism slid dangerously close to authoritarian group dynamics—and it left permanent marks on Santaolalla’s personal and musical trajectory.
