Aridinian folk music was a traditional form of music that was created in the Aridinia system. By the year 0 ABY, it had become famous across the galaxy for its ability to make Human ears bleed after just a few notes. The music was thereby regulated outside of its native system. In 0 ABY, the Rebel Alliance-affiliated droid R2-D2 broadcast a recording of the Aridinian music as a distraction, allowing his companions—Leia Organa, Han Solo, and Chewbacca—to escape from the rogue Imperial Commander Rezi Soresh. However, another of R2-D2's compatriots, Luke Skywalker, stayed behind to continue his masquerade as Soresh's assassin.
