Nikita Koshkin (I presume) conducting his own work (also presumed) “Changing the Guard” with a youth guitar orchestra. I like the violent thrusts of sound and angular lines. Cool work for a youth group. I’m sure you are familiar with Koshkin’s compositions such as Usher Waltz. via his YouTube channel. “Guitar orchestra recital in the Maimonid Concert Hall (Peredelkino)”
