I put this in Tangents category because there is many questions. First of all I love the Chicago Symphony and recently there seems to be more and more recordings from earlier days coming up. So questions is what trombone is Edward Kleinhammer playing in this video? Looks like an Thein but it cannot be? It's not a Bach? The tuba player is not Arnold Jacobs unless he did colour his hair?

Anyway, I love the energy and drive in the last movement.
