USA Underground is an independent music project spearheaded by producer ABBA-CONDA X4XX, focusing on the Hip-Hop genre. Their upcoming single, "Cypher I," will feature collaborations with Snazz D, GreyBarz, and Sean Doe, and is scheduled for release on August 22, 2025. The project deliberately maintains an underground presence with no official website or social media, and its stylistic influences draw from a diverse range of artists including J. Cole, Benny The Butcher, Kendrick Lamar, and even ABBA. The track will be available on Spotify through the August Sunset label.
