Experienced jazzmusicians that also could scat singing while ass trumpeting, this art of music expression was invented by pig-flatulence-singers(that also founded rusty gillespie) in the 1920s when jazz had it's raw form.
Jazzsingers often pushed a trumpet in their ass and started to fart while helping it by the scat-singing or even double trumpeting(from ass to mouth), the most famous ass trumpeter was DIZZY GILLESPIE who invented all kinds of gillespie-singing (mouth to pig ass, pig ass trumpeting, rusty gillespieing pig ass...), he often had several trumpetes by self and trumpeted in broadway.
The successor of dizzy gillespie was Scatman who is now the most famous rusty gillespie singer in the world, scatman mastered ass trumpeting in the 50s while having an accidental sexual event with a pig(olympigs 1950 in tokyo).
Scatman mastered his scat singing and ass trumpeting from the first to the last pig in his career of a pig championist and ass trumpeter
