Air Driver is an installation made from a series of brass loudspeakers constructed specially to be used by tuba player Robin Hayward. These loudspeakers are designed to be, like the tuba, simultaneously awkward and elegant. The piece can be set up for live performance or ongoing exhibition; during the latter recordings made from Hayward's unique extended-technique playing are broadcast through the loudspeakers. The title refers both to the human player that forces air through the hollow shaft of a brass instrument and to the brass speakers that vibrate the air in order to generate sound.
