John Medeski's trio have been experimenting with funk and jazz fusion for over two decades now, but there's no pretension there: it's all in good fun, with crazy improvised blasts clinging to unstoppable feel-good groves. And with the legendary Nels Cline lending his guitar wizardry, tonight's session looks to be groovier than most. Support comes courtesy of jazzbusters Resolution 88. Unreserved standing and seating on a first come, first served basis. Tickets usually £27.50 plus £1.50 booking fee.
