MIKHAIL CHEKALIN AND FRANK ZAPPA

From the Gost Zvuk label website:

For Russian electronic music, Mikhail Chekalin is not only a major character, who has affected the scene's establishment and development, but also a kind of symbolic figure. His music has been praised by many in the West - from journalists and critics of all kinds to Frank Zappa and Karlheinz Stockhausen.
While in Moscow Chekalin's name was excluded from the official cultural agenda for a long time: he was accused of propaganda of foreign 'pro-Western' aesthetics and up until the end of the 80's wasn't allowed to release his works or travel abroad.

(The late) Mikhail Cheklin's Bandcamp page includes (at least) one album that mentions Frank Zappa in the liner notes:
"The Return Of The Inferno"

Another meaningful encounter also occurred in the same ’90, that with Frank Zappa (having heard my „Night Pulsation“ he wished to meet me), this work might be doing homage partly to him, because improvising here plays its particular role, along with composing.
