This made my day the other night. The National Symphony Orchestra’s “In Your Neighborhood” program came to the Hill Center, bringing two NSO trombonists, two guest trombonists and a go-go band.
The only video I can find from the event is this one, and the sound isn’t great. But you get the idea, back and forth between the trombones and the band, including through this Imperial March, and later they all came together for a big finish. Will post it if/when I find it.
