I don't know who Maynard is, but my trumpeter friend told me many years ago that he went to see some collection/summit of trumpet superstars, I think they might have been accompanied by Tito Puente, and that one of the soloists was just getting higher and louder and higher and louder, and then his lips just exploded in blood!
He had to quickly turn around, cover his mouth . . .
Anyways, some of the most graceful stuff I've heard on a recording was actually by Marsalis playing Haydn. I had no idea a trumpet could be that graceful, but I've only heard it once.
