[1] In 1969 he along with several friends produced the children's "newsreel" anthology Happy Merry-Go-Round which quickly turned into a launching pad for young directors and a polygon for experimental animation.
In 1974 Sokolsky, Anatoly Petrov and Valery Ugarov tried to start another anthology series aimed at schoolchildren, but it was rejected by Goskino and the pilot was reedited into a 10-minute short Prodelkin at School.
Among them was Silver Hoof (1977) based on Pavel Bazhov's fairy tale; Little Mouse Pik (1978), an adaptation of Vitaly Bianki's short story about a little mouse lost in the woods; Ivashka from the Pioneers Palace (1981), a comedy fairy tale written by Eduard Uspensky; and The Adventures of Lolo the Penguin (1986-1987) which Sokolsky co-directed with Kenji Yoshida.
Sokolsky also directed a number of Fitil episodes, as well as animated sequences to several movies such as Sergei Gerasimov's The Love of Mankind (1972) and Alexander Mitta's How Czar Peter the Great Married Off His Moor (1976).
[2] An acclaimed composer Vladimir Martynov also regularly collaborated with the original Happy Merry-Go-Round team, introducing progressive electronic music to accompany animation.
