I could watch Tchaikovsky competition Gala concert and opera title is Lady mcbecth Of mtchensk and swan lake which is so famous ballet even If I bought cheap seat it was perfect view to watch the performances and I felt like Inside Of palaces. But I really hated audienes around me was using cell phone during all performances Or recording the performances was so bothering my eyesight.
