Helios is a DJ collective and party series founded by the Tallinn trio Tanel, Arto, and Jaan, which has its roots on the second floor of HALL and has since crossed national borders, expanding its sonic reach from Helsinki to The Hague.

The Helios nights offer a wide range of genre-blending tracks, weaving together the experimental spirit of 80s electro, the psychedelic power of 90s trance and techno, and the sleekly polished energy of 2000s minimal.

Over the years, Helios has invited many internationally known names to share the stage and decks, like Z@p, Gabbs, Raphael Carrau, Hicham, and Matthias, to name a few.

At I Land Sound 2025, the group will curate the Saturday night program at Piidvabrik.
