Igor Khoroshev was born in Moscow, Russia. He took piano lessons from age four and later learned other instruments including the trombone, French horn, guitar and drums. He obtained a diploma in music.
In the early 1990s, he moved to the USA, settling in Boston, where he worked with Benjamin Orr of The Cars among others. Khoroshev met Carl Jacobson of the Cakewalk software house. Jacobson employed Khoroshev, who composed music for Cakewalk’s Pro Audio 9, and he also introduced Khoroshev to Yes’s Jon Anderson.
Khoroshev released a solo album Piano Works in 1999. He appeared on the Emerson, Lake & Palmer tribute album Encores, Legends and Paradox. In March 2000, he and Jon Anderson worked on an album called True You, True Me. The album was estimated to be released in November of that year, with a tour as a duet in early 2001. This did not, however, come to fruition and the collaboration project was shelved.
Since leaving Yes, Khoroshev worked on film soundtracks, including “Good Night Valentino” and “The Pearl”, and in a production role, often working with Mike Plotnikoff (e.g. With Shivering Hearts We Wait, 2011)
