Amsterdam Dance Event—better known as ADE—attracts 400,000 people and 2000 world famous D.J.s, which makes it the largest electronic festival in the world. But that doesn’t necessarily mean rowdy crowds. The city is opening the doors of 140 venues—clubs, museums, even the central station—for live shows, techno, and last but not least some drum ‘n’ bass. Amsterdam is known for being ‘chill.’ See it while it’s wild! —E.C.
