This is not for the faint hearted, but well worth seeing.
Its a clip from a recording session of the film music to the movie Hellboy. And the sounds these dudes produces are just … well scary.
For any non-brass players I can tell you that to produce one of those “bursts” is hard. Really hard. To do 15 or so in a row is just amazing.
And now for something completely different. The best trombone player (not counting the bass trombone dudes above) in my opinion is Håkan Björkman. Here is a clip of him doing a cadenza of the Leopold Mozart’s Alto-trombone concerto. Very different - but still amazing.
Yeah - this is also something that shouldn’t be possible to accomplish. I have heared it live at the Stockholm Opera once.
