Or I could rent a car. When I get to the club, unhitch it, and open those doors wide. No stairs please. Hook up my speakers, monitors, etc. and hook into their mains. I stay in my living room drinking herbal tea, selling art off the wall, CDs out of bin, until it's time to play.
People can come on and have a look inside, and also hear from the mains.
This will work for other places, record stores with parking lots, university campus, house party. I kept seeing these trailers on my trips to Olympia this winter. You know they're a nice rounded shape and they have the windows around the front. The new mixes are in the correct running order. The sound is not as good as it could be.
