If that kind of thing ever happens again, this hypothetical virtuoso will have an expansive range to absorb and express. I think we haven't seen such folks yet much because this new music is so new. But some people come to mind. Subotnick, Ciani, Richard D. James, for a start.
I dunno about "angst" though. I'm not seeing a lot of that in forward looking music. Not sure why that is.
