The show features a "hidden camera" or surprise concept where famous vocalists and musical artists hide in everyday environments—such as cafes, gyms, or restaurants—and pretend to be just background music playing from a speaker, only to suddenly reveal they are singing completely live right in front of unsuspecting citizens.
