Anyway, when it comes to instrumental music, it'd be pretty difficult to distinguish between a young non-American act who'd learned all their chops from listening to old records and a young American act who'd learned all their chops from listening to old records.

And face it, in 2013, old records/the internet is mostly where their classic old-time influences will have come from.

I'd rather listen to a british americana act who'd learned from old Fiddlin John Carson albums than, say, an American act who'd learned from mainstream country radio. The point being everyone has access to everything now, so where you're from isn't so crucial to your musical development. America's a big country, so it's not like all American americana acts are getting their music direct from the source anyway!
