This is the first record in a long time that lists Gakkel' in the liner notes. We gurus aren't that great at telling a cello from a violin or whatever, but it's possible that this is the Boris-Seva reunion album. The notes don't tell who played on what song, of course.

The female chorus on the first track (Chizh singing about rumbling tanks) is a good SPB band, "Kollibri" (The Hummingbirds). Their own albums are better.
