Pollack first garnered the music world's attention when he became a prizewinner in the International Tchaikovsky Piano Competition in Moscow. Following, he concertized throughout the former Soviet Union and became the first American to record there for the Melodya label. Later, these were re-issued worldwide under several different labels. A CD entitled, “The Legendary Moscow Recitals” are from Melodya’s archives of Pollack recordings of his early years that sold in the millions throughout the former Soviet Union over several decades.

Among other international releases are Pollack’s Grammy-nominated CD for Naxos, the complete solo piano works of Samuel Barber, which was heralded as “prodigious pianism of fiery energy, dynamic articulation and élan,” Repertoire Magazine, Paris, France. Other CDs include an all-Chopin recital recorded in the Bolshoi Zal of the Philharmonic in St. Petersburg, Russia, released by Sony as well as two CDs of popular short romantic works for Four Winds.

Pollack has held several visiting artist faculty positions including The Juilliard School, Columbia University and Yale's School of Music. Pollack is also on the faculty at the Thornton School of Music of the University of Southern California, Los Angeles.
