Who is Igor Frolov, and who are his friends? One of Frolov’s best friends is violinist Piet Koornhof. Always on the lookout for unusual and appealing repertoire, Koornhof heard a recording of Frolov’s “Piece in Blues Style” and began his search for more music. Koornhof located many delightful pieces by Frolov, a Soviet composer and professor of violin at the Moscow Conservatory. Although jazz was banned in Soviet Russia, Frolov managed to incorporate the style into his compositions by going to foreign films and ultimately by traveling to Cuba.
