Kater Blau is a Berlin club with an outdoor area and party ship on the banks of the Spree in the Friedrichshain district, following in the tradition of its predecessor clubs Bar 25 and Kater Holzig.
Parties feature a wide range of house and techno DJs, from even locally rather unknown names to internationally known artists such as Claude VonStroke or Moonbootica.
But there are also many other cultural events, such as theater performances or concerts.
