Like others have said, it depends on the music, but it happens often for me. Having been on both sides of the music receiving/giving spectrum, I'd say it feels at least as good for the performer as it does for the audience as far as intense euporia is concerned. As a performer though, you are probably more likely to feel it as there is a greater chance of you connecting with at least one person in a large group of people versus being one member of the audience connecting with just one person performing. Being with a group of people as you experience this may have some effect on a single audience member, but probably not as much as it does on the performer. Not to mention the fact that as a performer you have a large group of people paying most if not all of their attention on you, which can be a rush on its own.
