We played freakin' Hartsfield--the busiest airport in the world, at least sometimes--right in the atrium between arrivals, dropoff, baggage claim, and the security checkpoint. Tile everywhere and a high dome skylight. Hundreds of people with nowhere to go.
And we had a soundman. (And roadies, sort of. Porters.)
We didn't realise until afterward how high energy it was. It was Moxie-like. We were starving. It being the airport, there was lots of food we couldn't afford.
Man, I'm doin' all my gigs at the airport from now on. The only way to fly.
