My band are considering playing at the Cavendish Arms in Stockwell sometime soon, because I like the sound of what they're trying to do on their Monday nights:

(20 min slot, use their backline, free entry, no pressure)

Does anyone have any suggestions of similarly low-key places to play in London where we can find our feet before playing more well known venues ?

I know London venues are a common topic on here so if anyone has happened to bookmark a link to any previous threads that would also be wonderful.
