Igor Khoroshev (born July 14, 1965 in Moscow, Russia, but living in the USA), is a musician best known as the keyboardist of Yes from 1998 to 2000. He appeared on their albums Open Your Eyes (released in 1997; Igor appeared as a session player on three tracks), The Ladder and House Of Yes: Live From House Of Blues. He is also trained to play guitar, bass, and drums, among other musical instruments. Coming from a classical background, after his departure from Yes he has composed soundtracks for motion pictures, and contributed at least 30 original compositions for Cakewalk's Pro Audio 9.
Khoroshev's brief stint with Yes was cut short by public allegations of sexual assault. Khoroshev then shifted his career to film composition, scoring a handful of minor films.
