It was an interesting scene in the movie.
It was 1965 during Dylan’s UK tour.
The guy was backstage complaining to Dylan that no one would hire him to perform, the guy’s implication being that his music was too advanced, or too cerebral, or something, like Dylan’s music, and yet Dylan got all this fame and fortune, but this guy couldn’t get a gig.
And Dylan was clearly skeptical, although he didn’t come right out and say it (Dylan is a very elliptical talker), but saying “Why do you think that is,” implied that maybe no one would hire him because the guy simply wasn’t very good.
Which applies to the AP courses.
I think I follow you. AP students are so smart, that they probably wouldn’t be hired for music gigs as, say, rappers or tejano players. But while they take some mastery of skill, you don’t have to be an AP student to swing those gigs. Just know your musical craft well enough. Bob Dylan being the obvious exception.
...I keeed!!! :-D
