Aleksey Rybnikov (Алексей Рыбников) was born in Moscow in 1946. He is perhaps best known for his film music - he wrote music for more than a hundred films. He also appears to have composed at least six symphonies, but no details are yet available.
This link indicates that if we follow it we will find "Symphony 6 part 2 (toccata)" but our poster in his title tells us to expect symphony 5. A contradiction that needs sorting out.

Here is his symphony no. 6:
