3. Lock Tavern (Camden)

35 Chalk Farm Rd.

Generally speaking Camden tends to have the most indie music venues (which isn't too surprising given its the capital of alternative culture in London), and the Lock Tavern is no exception.

This trendy music venue has an eclectic kind-of-feel to it, and has gained a massive following thanks to their ever-popular DJ nights every Wednesday. The venue also boasts an impressive beer garden (which some believe is one of the best in London) as well as mouth-watering Patty Smith burgers.

The venue has become famous for showcasing DJs as well as the best up-and-coming artists from a variety of different genres like electronic, disco and country; and although the name of the artists who perform here may not ring a bell, if you want to keep your finger on the pulse of the indie music movement in London, this is the place to be.
