“Disaster Area” is a fictional band from the second book (and television show) of the “Hitchhiker’s Guide to the Galaxy” series. As the Wikipedia entry puts it:
Disaster Area, claimed to be the loudest band in the universe, and in fact the loudest sound of any kind, anywhere. So loud is this band that the audience usually listens from the safe distance of thirty seven miles away in a well-built concrete bunker.
Hitchhikers.wikia.com adds that the “musicians themselves play their instruments by remote control from within a heavily insulated spaceship which stays in orbit around the planet – or more frequently around a completely different planet”.
