Just as I thought -- not a peep. So I'll carry on, then. Setsu, the protagonist, a country boy, leaves home when his grandfather, a tsugaru master, dies:https://youtu.be/FNIQcbQuTgM
He nearly gives up the shamisen, but circumstances find him onstage, filling in, until the rock musician the audience came for recovers from a temper tantrum:https://youtu.be/k6sjahxIvCA
Just imagine being 18, going to see the latest rock god, and having a hillbilly banjo picker come out instead (or substitute whatever cultural equivalent applies).
His brother comes to the city to check up on him, and they play a duet in the park -- one of my favorite scenes:https://youtu.be/CLFzx3v6svM
Then his manipulative mother shows up -- in keeping with anime tradition, a cold bitch must also be a hot MILF:https://youtu.be/Jdx3YfKYwKI
This, as I mentioned, is adapted from a long-running manga series, which is up to 25 collected volumes so far. I wonder how many countries could produce a similar comic book series about musicians?
