I just saw "The Singing Revolution," a documenty chock full of historical insight by Maureen and Jim Trusty. The Singing Revolution emerged in Estonia in 1987, during Soviet rule. After Gorbachev introduced Glasnost and Prerestroika, Estonians held mass gatherings of thousands upon thousands of people, where they sang paeans to their land and patriotic anthems - some of which resembled arena-rock balladry. Fifty years after the U.S.S.R. staked claim on Estonia by signing the Molotov-Ribbentrop Pact, the Baltic peoples formed a singing human chain that stretched 600 km from Estonia, through Lativa, and into Lithuania.
Three words: Best. Revolution. Ever.
