A film about the early chamber music ensemble "Kurant." Based on filming from 1986-1988. A concert featuring the ensemble was filmed in Leningrad, at the S. P. von Derviz mansion at 33 Galernaya Street, (then the Mayak club of the Admiralty Plant, 33 Krasnaya Street). Part of the filming took place inside the Rotunda at 57 Gorokhovaya Street. In the late 1960s and 1970s, the Rotunda regularly hosted informal gatherings of Leningrad youth. In the 1970s and 1980s, the Rotunda gained fame as a cult venue, attracting representatives of various subcultures—rockers, hippies, and punks.
