Having studied classical, as well as choral music, he has written six symphonies, several operas (including the first rock opera in the USSR - Ei, jūs tur!/ "Hey, you there!"), oratorios, cantatas, choir songs, a lot of movie and theater music. However, he is generally best known for his rock songs and is to be considered the first composer of intellectual rock music.
