Today Spendiaryan National Academic Opera and Ballet Theater ballet troupe will perform "Crystal Palace" Ballet under the recording as the theater orchestra will not participate in the performance. The information is announced on the theater's Facebook page. At the National Academic Theater of Opera and Ballet passions are stirred again. This time, the cause of the conflict is the retainer which wasn’t paid to the musicians of the orchestra. Last year the Armenian premiere of "Crystal Palace" ballet was held at the theater. Ballet dancers received their royalties, and orchestra members did not. Detailshere. []
