The influential jazz trumpeter Donald Byrd died on Monday, 2/4/13, at the age of 80, his nephew has said. Alex Bugnon, a jazz pianist, reported his uncle's death on Thursday, though it has yet to be confirmed. Bugnon wrote on his own Facebook page: "Donald passed away Monday in Delaware, where he lived. His funeral will be held in Detroit sometime next week. I have no more patience for this unnecessary shroud of secrecy placed over his death by certain members of his immediate family. "
