I didn't care too much for that selection Amelie. However I do share your like of jazz music. My son is a jazz trombonist. He started playing about 15 years ago and hasn't stopped yet. He played in a "big band" (jazz and swing) for many years. I love hearing them play! The louder the better.
Playing a trombone 15 years straight? Must be a record.
I didn't care for the selection either but I appreciate it more than a lot of what's out there, in terms of hip hop and metal and that trash.
In the movie Whiplash which was about jazz there was a sign on the wall that said something like "the musicians without talent can always joing rock bands."
