The "Rockestra" club of Ayb School has been presenting music theory, history, and its connection with other branches of art through lecture-concerts and open classes for 10 years. The core of the repertoire of the club's band, Battle of Evermore, consists of the best examples of classical and progressive rock. Artistic directors: Erik Aloyan, Vahagn Papayan. This year, as part of the 20th anniversary of the Ayb Educational Foundation and the 15th anniversary of Ayb School, Rockestra will perform a program titled "Why the beat?".
