In 1999, to wide acclaim, Ashot Ariyan performed his own “Concerto-Brevis” for piano and orchestra in the Great Hall of the Moscow Conservatory, accompanied by the Russian Philharmonic Orchestra. In 2009 his symphonic fresco “Sounds of Stonehenge” was performed in Montreal by the UdeM Symphony Orchestra. Later, in January 2011, the same work was performed in Armenia by the National Philharmonic Orchestra and in Moscow by the Moscow State Orchestra. His recent work, Planète X (Un train pour l’enfer II) for seven instruments, was performed in Montreal with great success by the Arkea ensemble in November 2013. Many of his chamber works were first performed at the Moscow Autumn International Music Festival. One of his latest works is a Cycle of 12 Fugues and Postludes for piano, commissioned by the Region of Waterloo Art Fund. In 2016 his music accompanied a presentation of the ballet "Two Suns," directed by Rudolf Kharatian and dedicated to the Centennial of the Armenian genocide.
