The original three-day festival was subtitled “Glastnost Rock - Rock for Peace!" and was held during a time of increasing defiance against Soviet rule. The free event attracted 190,000 people.
Rock Summer was then repeated nearly every year for the following decade, attracting names like Iggy Pop and Shaggy to what was otherwise a backwater of the international music circuit. The last time it was held was 1997, after which the organizers went bankrupt.
Rock Summer 25 will be held at the Tallinn Song Festival Grounds on June 15 and 16.
