A Colossal Weekend 2026

A Colossal Weekend is Copenhagen's festival for heavy, loud, and uncompromising music — a three-day deep dive into the heavier end of the spectrum, from doom and sludge to post-metal, noise rock, and experimental heaviness. The festival brings together a carefully curated lineup of international underground acts alongside Danish bands pushing the boundaries of heavy music.

Taking place in May at Store VEGA, one of Copenhagen's most beloved concert venues, A Colossal Weekend offers an indoor festival experience with exceptional sound and an atmosphere built for devoted fans rather than casual festivalgoers. It's the kind of event where every band on the bill was chosen with purpose, and the crowd knows it.

The 2026 edition runs May 7–9 with a full lineup of Danish and international acts. If your idea of a perfect weekend involves crushing riffs and ringing ears, this is it.
