There are few places in London where you can see big-name DJs on pub-sized soundsystems but The Lock Tavern in Camden, which celebrates its tenth birthday across the whole of May, was among the first. Celebrate tonight at Alvin C's (Wall of Sound) long-running electro-disco-Balearic-pop party, with guest DJ sets from Olubenga (Metronomy) and Alvin C tonight.
