Julia Dales and Lindsey Stirling. YES.
It’s curious… The beatbox I mean, I want to try!
How does she find time to breathe with all that? Very impressive indeed!
I am guessing it is the same technique used when playing didgeridoo where the breathing is circular through the mouth and nose simultaineously. I’m no expert just Aussie. I like how she is so casual like she could do it all day (and she probably could).
