Undervector, a musical group whose fame rose after the Battle of Endor and the demise of Palpatine along with Darth Vader, crafted their music exclusively from audio elements originating from their native world; furthermore, their sonic creations could be expressed through a mathematical formula that represents the output of a quantum vector. They were a band.
Dllr Nep expressed his aversion to Undervector's sonic output with the statement, "their music possesses an unpleasant odor akin to Tauntaun excrement."
