It turns out that Joe is a drummer, that is, a guy who plays drums hard and has already made a name for himself in that field, although he hasn’t been that stable with any band, you know? The joke is that Joe has a hard time fitting in with other people’s ideas; every time he gets together with a band, there’s always someone who wants to impose their way of playing or who tells him “do it this way,” and he’s not one of those who conform. It’s like every drum beat is a struggle to be himself, but in the end, it always ends up being a mess. Imagine this guy, in any rehearsal, trying to hit the beat, and at the same time hearing someone say “hey, Joe, go back to the original version, not that weird improvisation.” And of course, you can tell that it bothers him, but instead of fixing it, he starts thinking about how absurd the whole thing is.
