You are correct about that!
Sounds like you have “been there”! :-)
Yes, been there and have the t-shirt. lol
Musicians often forget the visual and entertainment aspects of performing. Its not enough to be good; you have to look good and make others feel good. In many respects, its a show, albeit one on a small scale.
Once the crowd is energized, the performers feed off the crowd. The its a virtuous cycle!
Good luck in your musical endeavors. Its a special privilege to enjoy.
