For lovers of the noisier kinds of rock music, Drone is not a bad choice. They regularly feature local bands of the more experimental kind, as well as DJ sessions. And they have great cocktails and cheap beers.
Go here for some rock'n'roll mayhem. Downstairs is a small basement, where the shows take place. Upstairs, the bar is usually packed, always until the early morning, so you can get in late without missing any of the action.
Look out for drinks specials and check up on upcoming events on their facebook page.
