One thing I love about living in London now is that I very rarely, if ever, have a lack of people to go to gigs with. On the topic of small venues (and in an attempt to stay on topic), the Amersham Arms in New Cross is pretty good. Until around October last year it was just an old man's pub that ocassionally had jazz or comedy nights, but it was then bought up by the owners of Camden's Lock Tavern, and has now become one of the busiest small venues in the city. Admittedly, as a pub it is now expensive and horribly trendy, full of Vice Magazine types (and copies of the magazine), but the gigs are great. Since reopening, it's had bands such as British Sea Power, Holy Fuck, The Field, No Age and Cadence Weapon, off the top of my head alone. As a venue, it's intimate and the sound isn't bad, plus it's just down the road from me, which is a plus.
