This huge German festival is situated inside a vast former airport, perfect for industrial partying but complemented with a wide-ranging lineup that offers big names from pop, rock, hip hop and dance. Björk, the unofficial queen of Iceland, plays the last show on her Biophilia tour on Saturday night, endearing indie scruffsters Blur and veteran synth-pop duo Pet Shop Boys are two more big names, and distortion-wrangling geniuses My Bloody Valentine are sure to draw a huge crowd as well. When nighttime draws in and the main stages shut down, you can carry on the fun with various techno-flavoured afterparties in aeroplane hangars.
