Electro-trash is a music style that Kozmo Sundrel IV, a student at Reena University, enjoyed listening to. In approximately 396 BBY, during the Queen's Bloom Festival day, Sundrel played electro-trash loudly from his speeder as he, along with his classmates Leyli Romero and Axel Greylark, secretly left the Reena University grounds to avoid their assigned volunteer work at the festival.
The electro-trash genre was featured in "The Queen's Bloom," a short story by Zoraida Córdova. It was included in the 2023 young-adult collection called The High Republic: Tales of Light and Life, which is a component of the larger Star Wars: The High Republic cross-media initiative.
