The Isle of Grub Festival was a five-day music festival held on the Isle of Grub on Ferenginar. Advertised as "Five Days of Music, Oo-mox, and Merchandising," the festival attracted almost a million participants, most of them drawn to the performance by Success scheduled for the final night. However, Success withdrew late from the festival, and were replaced by the mecho-accordian band Sound of One Lobe Flapping. Angry fans rioted, injuring a hundred thousand and burning every structure on the island to the ground.

Success later released an album In Memory of the Fallen, a Tribute to the Tragedy at Grub to honor those killed and injured. (DS9 reference: Legends of the Ferengi)
