Most artists at most festivals get one light…the sun.
Playing outside in the day time. Hot and blindingly bright.
You’re playing with the lights on unless you’re the headliner or almost the headliner. Fully illuminated. Fully exposed. Brightly lit you.
No lights to help stimulate the audience. No lights to guide the audience’s attention. No black outs between songs to help mitigate the silence. No darkness to hide the faces of the crowd. No lasers. No smoke machine.
You’re left with the raw connective power of your songs and performance.
So if you can win a crowd at a festival with the lights on, you can win pretty much anywhere.
