Shluur was a smazzo percussive ensemble composed of musicians from more than two dozen species that toured the galaxy doing musical performances. They once visited the Purghom Musical Performance Hall in the Bith capital city of Weogar on the planet Clak'dor VII for a two-week-long series of sellout concerts. One of the group's arrangers, the male Wookiee named Wurokkk, used these shows as an experiment on Bith vibrations based on biorhythms and brainwave patterns by composing a piece that caused aggressive behavior in the Bith. After an investigation uncovered Wurokkk's secret, the Wookiee was escorted off-planet.
