What is "subclub"

Subclub (formerly also known as U.Club and Účko) is an underground music club in Bratislava, Slovakia. It's located in one of the many emergency military storage bunkers and tunnels stretching under the Bratislava castle. The club is known for hosting alternative and electronic music nights, such as the well-known techno parties organized by Subtech during the 1990s. Today the club houses an extraordinarily wide range of other significant musical events in the city, including drum&bass, techno, minimal techno, electro, alternative rock, punk, metal, reggae, ska and crossover clubnights. Subclub played a major role in developing the Slovak Techno sound of artists such as Toky ( Rumenige), Loktibrada and DJ Boss and serves as the base outlet for the well-known Bratislavian minimal electronic label LFB.
