Bravo ! But it is a shame to have made so many cuts in the original score because it harms the development of the musical text of this beautiful first movement of the concerto. Then, having played certain passages at a lower octave is a good choice, taking into account the use of a Bb tuba which offers a better sound in the mid and bass than in the treble. I'm making my comment even though the video is already 6 years old. I think that the tuba player, who already had talent, has since had a good career and has perhaps had the opportunity to replay the entire piece with piano, fanfare or orchestra.
