Formed in 2016, Heleven have developed an alternative metal sound marked by technical chops, intense atmospheres and bold ambition. Their single ‘Stronger’ heralded a darker, heavier shift, and the album ‘New Horizons Pt. I’ (2023) broadens their horizons. At the Rock Imperium Festival, Heleven will stand for the next wave — unafraid to explore, to fuse, to break boundaries.
