1970s in Moscow. In March 1976, Tallinn (ESSR) hosted the "Tallinn Youth Songs" Rock Festival, which brought together bands from different republics of the Soviet Union. During this period, not album recordings, but concert recordings were mainly distributed, which were rewritten as self—published from one owner of the tape recorder to another. Since '79, underground recording studios have been appearing (AnTrop, Sverdlovsk studio etc.). For Leningrad, the concept of acoustic kvartirnik (house concert) was spread; Moscow bands performed mainly in electricity. "Ruby Attack", "Argonauts", "Mify", "Successful Acquisition", "Mashina Vremeni", "Sankt-Peterburg", "Rossiyane", "Vysokosnoe leto", "Autograph", "Voskreseniye" were among the main groups of the 1970's underground scene. Most of them were influenced by the styles of art rock, hard rock and progressive rock. Among the first officially published full-length rock albums are called "Russian pictures" VIA "Ariel" (1977), "Guslar" VIA "Pesnyary" (1979). Some Soviet composers of the turn of the 70s - 80s worked in the rock opera format; the most famous works are: "Orpheus and Eurydice" (1975), "The Star and the Death of Joaquin Murieta" (1978), "Juno and Avos" (1981).

Bands such as Voskreseniye, Alisa, Autograph, Kino, Mashina Vremeni, Nautilus Pompilius, Aquarium, Secret, Piknik, DDT, Krematorij, Grazhdanskaya Oborona, and Agatha Christie became influential in the development of the genre, with subsequent artists influenced by their style. At the same time, many bands of the 1980s were, in a sense, a group accompanying a songwriter. Often bands were formed around such an author of lyrics (and sometimes music), who was usually considered a "leader" and, just like the band, became widely known. In 1980, Spring Rhythms: Tbilisi-80 took place in Tbilisi in the Georgian SSR. It was the first official rock festival in the Soviet Union. Almost all the performers and prize-winners at the festival were rock groups from the Russian SFSR. The "Fiztech—1982" festival actually launched the popularity of new wave. In the late 1970s and early 1980s, a lot of amateur bands who signed labor agreements and contracts with various philharmonic societies of the USSR, such as "Mashina Vremeni", "Zemlyane", "Autograph", "Cruise", "Dialog", and others, were able to break into professional
