Wow, and I thought Sonar By Day was intense…Spread across two cavernous halls in a massive convention center south of town, Sonar By Night has four stages – two inside, two outside – with enough room for 50,000 people. There are both DJs and live bands, reasonable drink prices, and plenty of room to room around. I feel like a kid at a carnival. Literally: there's even a bumper car ride adjacent to the SonarCar stage, which you can ride for 5 euros. Soooo much cooler than the one at Coney. (Pictured: Cut Copy on the SonarLab stage.)
