I have played rooms where the audience outnumbered my mailing list and rooms where the front row could read my setlist upside down. The small ones are the ones I’d save from a fire.
What the back wall hears
In a small room there is nowhere for a song to hide. No light show to carry a weak second verse, no distance to blur a flat note. When it works — and some nights it truly works — eighty strangers breathe in the same place, and the quiet between songs is louder than the songs.
Book the small room. Bring your friends. That’s the whole economy of this life.
