Why this event matters

Brazilian National Library and municipal material confirm that Festival de Águas Claras had four editions: 1975, 1981, 1983 and 1984, centred on Fazenda Santa Virgínia in Iacanga, São Paulo state.

Problems, conflict and practical limits

Attendance and edition-specific lineups vary by source. A 2025 Iacanga municipal document explicitly remembers the 1975 festival, its 17 January start and the fact that it proceeded without the required authorisation, after which authorities reacted against large open-air events.
