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).
