Short answers, pulled from the story.
Boris Grebenshchikov and Anatoly Gunitsky formed Aquarium in Leningrad during 1972. Grebenshchikov was a student of applied mathematics at Leningrad State University while Gunitsky worked as a playwright and absurdist poet.
Aquarium performed their first live concert in March 1973 at either a small country venue or the Leningrad restaurant Hold located within Central Park of Culture and Recreation. The group received fifty rubles in cash for this initial performance.
Grebenshchikov lost his job and was expelled from the Komsomol Young Communist's League following the 1980 Tbilisi Rock Festival incident. The jury members demonstratively left the hall due to provocative movements made by Grebenshchikov during the set.
In 1987 Aquarium recorded their first album for the state-owned Melodiya record label which became a huge hit selling well over a million copies within a few months. This release occurred during the second half of the 1980s when Glasnost allowed underground musicians public recognition.
Aquarium performed for the first time at the Royal Albert Hall in London on an unspecified date in 2007 marking another international milestone for the band. The group continued to tour extensively over the former Soviet Union Eastern Europe and places with Russian-speaking immigrant communities in Germany Israel and the United States.
