ENTPs are prone to performances of all kinds because they're ExxP--outwardly focused, comfortable with crowds and very spontaneous.
The INTs, I've noticed, are often way too shy to attempt a performance at anything that isn't a really serious area of interest, and when they do they will take it deadly seriously and tear themselves up over the tiniest mistakes. Frequently they're just too damn self-conscious to bother doing anything performance-like in front of people, but if they muster the motivation and courage, you can expect the highest degree of technical competence in their abilities. (And not a shred of levity...whatever the INT is truly interested in is SERIOUS SHIT!)
The ENTJs will also perform sometimes, and when they do they're really good at whatever it is they're performing. They can have trouble working in groups that require collective creativity (like, say...bands) though, and also they're not as willing to work on something just for the joy of showing off like an ExxP. They want to see some deeper purpose for it, which unfortunately ends up leading them away from the arts often times because at first it really is kind of pointless (at least from a purely rational standpoint)...you have to do it for a long time to become proficient enough for any other serious goals to even be remotely realistic, and that's kind of a turnoff for an NTJ if s/he doesn't REALLY love the arts.
