UNLEASHED is a sex-positive kinky techno party in Berlin, produced under the name UNDR. It runs at INSOMNIA Berlin, a club listed separately in this directory, and holds no premises of its own.

By its own account it began as a hobby and grew out of a dilemma its organisers describe plainly: either intimate kink-first gatherings with the music as an afterthought, or full-blown techno raves. They set out to refuse the choice. The night is billed as a two-floor peak-time techno rave with harder sounds in the room it calls the Dungeon, and it labels itself with three words — techno, kinky, fetish.

Its next edition when this page was written was a Saturday, 26 September 2026, with doors at 10pm. Tickets are sold in advance through Resident Advisor and its own site, and it publishes a dress code, a set of rules, an FAQ, a news section and a merchandise shop. It also runs a German-language version of the site.
