Protivofazza (English: Antiphase) is the fourth and final album by Russian rock band Gorky Park, released in 1998, originally under Nox Music in Russia.

Most songs from both albums were recorded in the same sessions in Los Angeles in 1994, because originally the band thought to release a double album (twenty-one songs were recorded and mixed that year), project that was finally discarded.

In 1996, they quickly recorded only two new songs composed by Alexei Belov, to complete the fourth album.

For this work, the group had softened its sound considerably, with an extensive use of keyboards instead of electric guitar in most songs.

For its concept and name "Protivofazza”, the band said: "There is a term in electronics, when one phase over the other flips and sound is not what it should be.
