Skip to about 1 minute, unless you would like a lesson in the finer arts of vuvuzela playing. As much as vuvuzelas seem to be the funniest thing in the world right now according to popular opinion, the only thing that made me want to post this is the fact that they are playing trombone excerpts. It makes sense. The mouthpieces (if you can claim that they have one) are roughly the same size, and the range seems similar. It still kind of hurts me.
It took some digging through German websites, but I have determined that the people playing are probably Uwe Saegebarth, a trumpet player, Helge von Niswandt, trombone, and either Stephan Stadtfeld (trumpet) or Stefan Gorasdza (french horn), all of the Konzerthausorchester Berlin. The spelling in the subtitles leads me to think that the Stephan in question is the trumpet player. I am at least satisfied that the person playing the Boléro solo was, in fact the trombone player.
