Not a thing
Not a thing. are non-profit promoters - this means they generally pay for spaces themselves out of pocket, and split ticket fees equally between bands and other people working on the night.
They run 4 to 6 nights each month, across genres including alt-jazz/soul, alt-rock/post-punk/shoegaze/noise and global beats. They also run a number of nights with new and interesting formats, aiming to create the most spaces for new and upcoming bands. That's where the name comes from originally - the formats and the nights they run aren't 'a thing' until they are.
