As isdapi said in the
unromanized artists thread, Hiroshi Minami could be a wrong romanization of Hiroyuki Minami. However, I think that Hiroshi is the correct and Hiroyuki is the wrong romanization of this horn player.
First,
Drillspin gives the name reading as Hiroshi. Also,
a post from this blog talk about the 60th birthday party of a horn player named Hiroshi Minami. As far as I understand from Google Translator result, it’s written by a horn student. If he is the same person of this profile, I’m more inclined to believe in a person supposedly close to him.
However, there are more credits as Hiroyuki rather than Hiroshi. In other albums he is credited with the kanji name.
