Volunteer-run, paired down and unpretentious, The Vortex on Gillett Square has the distinction of being one of the UK's premier jazz venues, hosting nearly 400 contemporary, experimental and improv jazz gigs a year, including a cast of well-known musicians. Aspiring vocalists can also find a stage here at the open mic sessions backed by the house band. For the best sound, head towards the middle of the room.
