I tried to google, but couldn't really find any help.
In the track "Waterfall Fight" on the Black Panther score (not the soundtrack), I could swear it sounds like they used didgeridoos. I know the composer was going for the "tribal" feel, which makes sense, but it just takes me out of the track a little bit, given that didgeridoos are Australian tribal, not African.
So I was wondering either
a) were they, in fact, didgeridoos? or
b) is there some African tribal instrument that sounds similar to didgeridoos?
