HEISA’s sound draws from influences like Black Midi, Tool, Battles and Swans, blending dissonance with a strong sense of identity. Their music balances chaos and control, mixing unsettling atmospheres with hypnotic rhythms and sharp distortion. HEISA crafts tightly arranged, complex compositions featuring heavy guitars and vocals that merge seamlessly with their bombastic, primal drumming.

Formed in Limburg (BE), HEISA quickly made a name for themselves with raw, energetic live performances. Just like the mines in their hometowns, the live shows of HEISA are dark, eerie, thrilling, and full of intensity, drawing the audience deep into an immersive atmosphere where the energy builds, and unexpected moments erupt like bursts of light in the darkness.

In 2020, their album joni was released, although the pandemic canceled live shows. Nevertheless, joni’s ten tracks resonated with listeners around the world, receiving airplay and earning glowing reviews. Critics praised their ability to both challenge and captivate audiences, solidifying HEISA as one of the most exciting new acts in the scene.

In 2025, HEISA embarks on a new chapter with the release of their third album. This album showcases an evolution in their sound, keeping the bombastic drums, droning guitars, and dynamic vocals, but pushing further into melody and experimentation. The first single, “The Harmonist,” blends heavy basslines with impactful drums, while the guitar acts as a secondary voice, guiding listeners through a feverish dreamscape. On this new record, HEISA brings their emotions to the forefront, revealing a raw, edgy intensity in tracks like “Lazar” and “Sad Dancer,” where vulnerability and tension intertwine. TROIS will be released on March 28 via Labelman, marking a new phase in HEISA’s musical journey.
