With a reputation for pushing bass music into earth-shaking territory, Aftershock—the bass-focused sub-brand of Relentless Beats—is launching a brand-new Halloween experience this fall. Titled HEX, the inaugural edition arrives October 30–31 at the Rawhide Festival Grounds in Arizona, transforming the venue into a two-night, two-stage bass music ritual designed for maximum impact.
Positioned as a “Bass Music Halloween Experience,” HEX marks a new chapter for the Southwest’s rapidly expanding electronic scene. The event blends heavy production, immersive Halloween aesthetics, and a lineup built for pure low-end destruction, reinforcing Aftershock’s identity as a curator of high-intensity live experiences.
At the top of the lineup is dubstep powerhouse Subtronics, known for his signature “robot bass” sound design and high-energy performances. He is joined by bass titan Excision, whose earth-rattling sets have become a benchmark for modern festival production. Also featured is melodic bass artist INZO, bringing emotional depth and cinematic textures to the bill, alongside genre-bending duo ATLiens, known for their dark, atmospheric approach to bass music.
The lineup expands further with a deep roster of heavy hitters and rising underground names, including Badklaat, Decimate, Dennett, Hurtbox, Inaktiv, Izzy Vadim, Modal Nodes, Nikademis, Onara, Proxxy, Softest Hard, Sora, Xaebor, and YVM3, each contributing their own distinct spin on modern bass music culture.
Across two nights, HEX will unfold across two stages, delivering a curated blend of dubstep, experimental bass, riddim, and hybrid sounds designed to immerse attendees in a fully realized Halloween atmosphere. The festival’s concept leans into ritualistic energy, framing the experience as a sonic summoning of bass music’s heaviest forces.
All two-day ticket tiers for HEX go on sale Thursday, June 25 at 10 a.m. PST, with registration and updates available via Summon The Hex. The event is strictly 18+, with additional information available through Relentless Beats and its official social channels.
As Arizona continues to establish itself as a major hub for large-scale electronic music events, HEX arrives as a new seasonal tradition in the making—one built on volume, intensity, and a shared devotion to the heavier side of dance music.
