A 1972 concert by the Duke Ellington Orchestra in Buenos Aires, and a later appearance by trumpeter Dizzy Gillespie, inspired Boiarsky to become a jazz musician.
He took part in the local revivalist jazz scene of the mid-1970s as a clarinetist, and subsequently played the alto and tenor saxophones.
He returned to Argentina in 1982, and following two solo albums for CBS Records, he composed and performed incidental music for the Argentine science fiction film, Man Facing Southeast, in 1986.
Boiarsky joined Lionel Hampton's Orchestra, and in 1989, was named music director by the renowned vibraphonist.
He later collaborated with Jimmy Heath, Nancy Wilson, Al Di Meola, and Claudio Roditi, with whom he worked on a number of samba-jazz fusion recordings.
