Relentless Beats and Aftershock are introducing a two-day bass music festival to Arizona on October 30–31, bringing some of dubstep's biggest names to Rawhide Festival Grounds.
Halloween weekend in Arizona is getting a new addition to its electronic music calendar. Relentless Beats and its bass-focused sub-brand Aftershock are launching HEX, a two-day festival taking over Rawhide Festival Grounds on October 30–31, 2026, with Subtronics, Excision, INZO, and ATLiens leading a lineup built around the heavier side of electronic music.
Billed as a Bass Music Halloween Experience, HEX will feature two stages across both nights, bringing together established dubstep headliners, rising producers, and back-to-back performances. The festival arrives as another addition to Relentless Beats' growing roster of Arizona events, this time with a Halloween theme and a lineup dedicated almost entirely to bass music.
Friday, October 30, will be headlined by Subtronics, whose aggressive sound design and intricate production have made him one of the most recognizable names in modern dubstep. Known for tracks such as “Griztronics,” his collaboration with GRiZ, and releases including FRACTALS and TESSERACT, the Philadelphia producer has built a following through his combination of heavy bass, unexpected transitions, and elaborate live production.
Joining him Friday is INZO, whose music takes a different approach to bass, incorporating melodic arrangements, atmospheric production, and experimental elements. The first night will also feature Badklaat, Dennett, Inaktiv, Izzy Vadim, Layz, Nikademis, Onara, Sora, and Linz, giving festivalgoers a range of sounds across both stages.
Saturday, October 31, shifts the focus toward some of dubstep's heaviest performers, with Excision taking over as the night's headliner. A longtime figure in bass music, the Canadian producer has become known for his large-scale audiovisual productions and aggressive sound, making him a fitting choice for the festival's Halloween night.
ATLiens will also perform Saturday, bringing their masked identities and darker approach to electronic music to Rawhide. The duo's sound combines distorted bass, ominous melodies, and experimental production, fitting naturally into the festival's horror-inspired setting.
Saturday's lineup also includes Decimate, Hurtbox, Modal Nodes, Proxxxy, Softest Hard, Xaebor, YVM3, and Deathbeat. Riot Ten and PhaseOne will join forces for a back-to-back set, bringing together two artists known for their heavier approaches to dubstep and bass music.
Beyond the main lineup, HEX is giving local and emerging DJs an opportunity to perform through its Blood Oath DJ Competition. Scheduled for October 11 at Sunbar in Tempe, the competition requires artists to enter in pairs, with the winning duo earning an opening back-to-back slot at the festival.
A portion of the competition's proceeds will benefit Rosie's House, an Arizona nonprofit that works to expand access to music education for young people.
HEX also marks another expansion of Aftershock's presence in Arizona. As Relentless Beats' bass-focused brand, Aftershock has continued to bring heavier electronic music artists to the Southwest, with HEX adding a dedicated Halloween weekend event to its programming.
Rawhide Festival Grounds has become a familiar destination for large-scale electronic music events in the Valley, hosting festivals and touring productions throughout the year. With two stages and a lineup spanning different styles of dubstep and experimental bass, HEX will bring that festival setting into Halloween weekend.
The event also gives fans two different headlining experiences. Friday's lineup moves between the intricate production of Subtronics and the more atmospheric sounds of INZO, while Saturday brings Excision's heavier approach alongside the darker, experimental sound of ATLiens.
With Halloween falling on the festival's second night, HEX is positioned to become a new seasonal gathering for Arizona's bass music community, adding another two-day event to the Valley's fall festival calendar.
