Even with the bad acoustics and recording those performances are cringeworthy; having played in a small orchestra, if you can't make it through a piece in rehearsals, you don't perform it on stage. It is 'brave' to take on music above your level, but when we played what for us amateurs was considered challenging music (Nostradamus by Schwarz for instance), we would rehearse it for the great part of the year aside from our regular program until we got it down to sounding acceptable. Some pieces we never ended up playing because it just didn't work.
There is not enough appreciation in modern society for the arts, classical and film music. These guys need all the encouragement they can get. Maybe this is the best they can play, but they don't need some jackass on a forum laughing at them.
If there was no laughter in this world , it would be a sad place .
This is the board where certain people deride composers ( zimmer et al ) then on the other hand says you should not deride people when it was clear that the post was not deriding the musicians but the performance .
