Didgeridoo technique has been tried with Bronze Age horns (e.g. by taking replicas to Australia for Aboriginal didge players to have a go on) and it works. Which doesn't show that anybody played them that way before 2000, and if they did, there obviously weren't any tunes resembling present-day Irish folk for them to accompany. Still, interesting.

I wanna hear somebody reinvent the art of traditional Galloway lithophone.
