Tchaikovsky- Swan lake - bass trombone excerpt

Swan Lake by Tchaikovsky
Orchestra Filarmonica Italiana
Teatro degli Arcimboldi (Milan)
Today my colleague could not come to the theater, and I recorded this series of orchestral passages so as to emphasize the bass trombone excerpts.
It was a difficult day, but educationally interesting.
Ps. The bass tuba helps so much to play well
