Aquarium or Akvarium is a Russian rock group formed in Leningrad (now Saint Petersburg, Russia) in 1972 by two friends: Boris Grebenshchikov, then a student of Applied Mathematics at Leningrad State University, and Anatoly (George) Gunitsky, a playwright and absurdist poet. The founding members were Grebenshikov, George (drums), Tsatsanidi Alexander (bass), Alexander Vasilyev (keyboards), Valery warmed (sound).
The popular story behind the name "Aquarium" is that it was inspired by the Budapest street Leningrad pub "The Aquarium" and suggested by one of the band members. However, Grebenshchikov has given differing stories in interviews, suggesting alternately that it came through band word association sessions or was inspired a glass aquarium-like building.
In late 1972, guitarist Edmund Shkliarsky (later the leader of "Picnic" band) was briefly a member of the band. Bass player Michael Feinstein-Vasiliev (Fan), the first professional musician in the "Aquarium", joined in January 1973. In the same year keyboardist Andrew "Dyusha" Romanov also joined the band, and, inspired by rock-flautists Richard Meier and Ian Anderson, retrained as a flautist.
