Roadie

The road crew (or roadies) are the technicians who travel with a band on tour, usually in sleeper buses, and handle every part of the concert productions except actually performing the music with the musicians.

This catch-all term covers tour managers, production managers, stage managers, front of house and monitor engineers, guitar techs, bass techs, drum techs, keyboard techs, lighting techs, pyrotechnic techs, and security/bodyguards, among others.
