RVLTN teams up with Insomniac to bring Australian electronic producer What So Not to Substance at Neonopolis. The show transforms the venue's industrial-meets-futuristic atmosphere into a proper bass-driven party, with What So Not's genre-blending sound—think trap, future bass, and experimental electronic—filling the space. Known for tracks that move between melodic builds and heavy drops, his sets tend to keep the energy shifting throughout the night.

Substance's setup works well for this kind of show, with its LED walls and sound system designed to handle the low-end heavy production that What So Not brings. The "and more" on the bill suggests additional acts will round out the lineup, likely featuring support from other electronic artists in similar lanes. At 21+, the crowd typically skews toward electronic music fans who know the difference between subgenres and aren't afraid to get lost in the music when the bass hits.
