Technostate BIGBANG Halloween (Stockholm, Sweden) 2026

Technostate puts its two biggest concepts on the same night for the first time on Saturday 31 October 2026, combining BIGBANG with its long running Halloween party at Annexet, the hall attached to Avicii Arena in Stockholm. Doors run from 10pm to 4am and entry is 18 and over. The Swedish promoter has staged a Halloween event five years in a row and calls this its most ambitious production so far, with a full width stage, psychedelic visuals and a laser and light rig scaled for an arena room rather than a club.

Ummet Ozcan, Astral Projection, Blastoyz and Evertwo are confirmed, with further names still to be announced. The billing leans psytrance: Astral Projection are among the acts that built the Israeli scene in the 1990s, and Blastoyz has carried the harder end of that sound into main stage sets across Europe. Ummet Ozcan brings a different register, having moved between trance and big room through his career, which gives the night a broader range than a single genre bill.

The dress code is left open, with the organisers asking for anything from full costume to rave ready, and a prize is given for the best costume on the night. Tickets are sold through AXS. Annexet sits in the Johanneshov arena complex in southern Stockholm, served directly by the Globen metro stop, which makes it one of the easiest large indoor venues in the city to reach late at night. For Sweden the date has become a fixed point in the music festival calendar rather than just another club booking.
