Listening to music can have an effect on my mood but I don't think I ever get high from it.

Performing for me is limited to floor spots and usually the feelings I get are nervousness and relief when I've done my bit. On extremely rare say 3 or 4 times in 30 years) occasions, I have had the feeling the audience is almost under my control, hear and feel the silence when doing my piece and then when it's over an extended silence before (believe or not!) an ovation. I find it quite eerie but I suppose if I got high from it, it would be from some form of ego trip rather than from the music.

It may apply to other forms of joining in but I'd say the only time I get high from music is the occasion when a session goes up that extra gear and everyone seems to just be magically swept along by the music.
