There’s a palpably British feel to the music made by this sextet of improvisers, all of whom are based in, or have strong links to, the Midlands and the North. Certainly, many of the strategies employed here were originally birthed in that first flowering of UK free improv in the mid-1960s – approaches that have continued to be explored and developed to the extent that this kind of non-idiomatic improvisation is, ironically, now a recognisably distinct idiom of its own. All three of these live tracks (two half-hour sets and a short encore), start tentatively, with no one musician willing to strike out too early. Mwamba’s dreamy vibes billow and shimmer in the heat haze of Mark Sanders cymbals while the horns mutter to themselves. It feels like an awkward conversation everyone is reluctant to start. Things heat up considerably when Paul Dunmall opens the throttle on his full- throated tenor, sending Sanders and bassist Seth Bennett into a bullish free-jazz tumble that encourages fleet-fingered sopranino runs from Paul Coates. So why waste time being so polite?
