Nobody's Darling: Japanese Bluegrass Band

First, and completely independently of the cultural dust-up, I've long loved Japanese bluegrass. I'm way psyched that folks from a culture about as different as its possible to be recognize the awesomeness of bluegrass and old time. Second, they're just damn good at it. From the first notes of this you can tell that they're on point and just get it.
But, since we're on the topic anyway: "cultural appropriation" is bullshit.
Culture is "appropriation" if it's anything; it's "that which is passed down."
Anyway: keep it up, Japanese bros; you absolutely get it.
