I know I share a lot of Jacob Collier content, but this one is particularly interesting because you can see him learning things in real-time, exploring an instrument that is not his native tongue but he’s already world-class in. It’s so interesting to me the polymath musician friends I have who can play so many instruments how they bring the technique and language across their learning, and this video illustrates it well.
My friend Ed Aten recommended this amazing Bernstein clip:

Which hopefully leads you to the excellent Maestro film.
for a sec, I thought that was you jamming with Jacob!
