After a sold out and successful 909 festival this summer in Het Amsterdamse Bos, 909 returns with a special indoor edition at Mediahaven Amsterdam. The Mediahaven location consists of three connected areas with first-class facilities. The rooms vary from a 12-metre high ceiling to a basement with a grungier feel to it. This event will be studded with high-quality artists and the finest sound systems. All in honour of the legendary Roland 909 rhythm composer.
