Sound of One Lobe Flapping was a seven-person mecho-accordian band on Ferenginar. They played at the Isle of Grub Festival, and had the poor fortune to have appeared on stage at the same time the popular group Success had been slated to play. Festival participants stormed the stage in anger, and all the members of Sound of One Lobe Flapping disappeared without a trace. (DS9 reference: Legends of the Ferengi)
