Outside World Festival Raveolution (Garbsen, Germany) 2027

Outside World Festival brings its Raveolution edition to the Blauer See in Garbsen on 3 September 2027, running from 2pm to midnight on the lake north west of Hannover. The organisers bill Outside World as the largest techno classics festival in Germany, and it has operated since 2018 as a touring brand rather than a single annual event.

The format is built on rave classics: the trance, hard trance and techno records of the 1990s and early 2000s, played by the DJs who made them. Raveolution is the strand that has grown fastest, with its own aftermovies and a reunion series that runs indoors through the winter. Bass-D and other names from the Dutch and German hardcore scene have appeared on recent Raveolution bills.

The wider Outside World calendar covers seven cities across Germany, with dates in Hannover, Hamburg, Bielefeld, Osnabrueck, Dresden, Braunschweig and Halle through the year, and a separate Rave Repeat series. Tickets for all of them are sold through the official site. Garbsen sits 15 minutes north west of Hannover with its own S-Bahn connection. For rave classics in northern Germany, it is the music festival brand with the widest footprint.
