Most people want a great time way more than they want great musicians.
Yes, it helps to have great musicians in order to arrive at a good time…but by no means is it necessary. Why do (some) bad bands draw a big crowd? Because they understand this concept.
People want a show, a thrill, a chorus, a lead singer, a vibe, a story, some attitude, an arc, something worth talking about.
Why are people gonna be glad they saw your show?
And whatever your answer is, rehearse it, grow it, feed into it, make it the main thing.
