Aram Khachaturian conquered the world with the boundless delight he took in composing. His Sabre Dance found its place in advertising, his Adagio from the ballet Spartacus accompanied a cult series, and prominent ice skating pairs danced their way into the hearts of their spectators to the Waltz from his stage music to Lermontov's Masquerade. On the other side, his symphonic music and concertante works even today continue to attract the greatest conductors and soloists. A unique, often imitated, but never reproduced synthesis consisting of fascinating instrumental virtuosity, exotic melodies, highly imaginative harmonies, and irresistible rhythmic spirit distinguishes the three concertos and three concert rhapsodies written by Aram Khachaturian during 1936-46 and 1961-67, and this double trilogy begins its cpo journey with the earliest and latest of these works.
