I need to figure out how to concisely describe my occupation... for tax purposes, I'm a self employed private contractor listed as a "sound technician". But I'm not actually an engineer or "technician"... I'm also not a "roadie" as I don't go "on the road" (touring). I get contracted by a music production/PA rental company to provide labor for setting up stage, lights and sound for events ranging from graduations and parties, to corporate events, to shows and concerts. But my relationship with the company I work with is as if I were actually an employee.
What I do is set up for any kind of live sound situation, and in a full work day I might load the trucks at the shop and unload them on site; build a stage; assemble lifts and truss; place speakers, monitors, lights, microphones and other musical equipment; assist in patching and setting up consoles; perform the duties of a stage hand or assist an engineer; then take everything down and load the trucks again when the show is done. The company I work with is based in Brooklyn but we do work all over the city, on Long Island, and even in New Jersey and Connecticut.
I also occasionally do woodwork and/or painting with a friend of the family.
