CortexUS — Suno AI prompt

CortexUS is an openly AI-assisted project based in Seattle, Washington, working the seam between horrorcore rap and industrial metal. It appeared in 2025 with the single «Psycho Circus» and expanded through 2026 with «Fix You», «Broken Toys» and «Feed Me», while «Not Broken» became the breakout, entering the Top 25 Hard Rock Songs listing at number 24 and carrying the project past 2,800 followers on Deezer alone. A longer release, «Hiphop is not dead but... [Retro Boomin Project Part 1]», arrived in September 2025 and shows how far the project reaches outside metal. The recordings are less uniform than the branding suggests, which is worth knowing before prompting. Metering five tracks returns tempos around 92 to 108 BPM and minor keys throughout, but loudness swings across seven decibels, from −11.4 to −18.1 LUFS, so there is no single mastering fingerprint to copy. The top end stays present — 14 to 27 percent of the energy above 2 kHz, spectral centroid between 830 and 1,379 Hz — and that is where the cymbals and guitar bite live. The prompt aims there: a voice worn raw, guitars tuned low and heavy, staged dread rather than plain volume.
