We've got a bunch of great musicians, noisemakers and freaks from the Bristol new-music underground, who will be drawing lots on the night to decide who is playing with whom. Sure to be a psychedelic car-crash and a glorious mess. 

Full roster for Mystery Vortex has been confirmed:

• Tina Hitchens (Harpoon, Tisla)
• Rebecca Sneddon (Yoke, Free Nelson Mandoomjazz)
• Joe Kelly (Wendy Misma, Spunking Octochoke)
• Annie Gardiner (MARCY, Olanza)
• Simon Mawsom (Traumkl, Action Beat)
• D-M Withers (Bellies!, Fingertight)
• Dan Johnson (EP/64)
• Owen Chambers (Carnivorous Plants)
• Charlie Miles (Zero Gravity Tea Ceremony)
• Louie Newlands
• Tony Gordon
• Tara Baggott

All ensembles will be completely random and decided immediately before the performance.
