Bone Battle

We love a bit of bone bashing here at Time Out, and this opportunity to witness two brass virtuosos clash trombones in a musical battle sounds like a whole load of brilliant fun. Ashley Slater of '90s funk-pop band Freak Power and Jerome Harper of London nine-piece Brassroots go head-to-head, each playing a 30-min improv set. Who's got the best bone-handling skills? There's only one way to find out.
