It's a high point in any live recording featuring Han Bennink when the drummer starts to let out a whoop or two of pleasure and surprise – and it doesn't take too long before he's having the right amount of fun on this latest from a transatlantic ensemble dedicated to reinterpreting and exploring the compositions of Steve Lacy. In the live setting, they move away from the carefully mapped reimaginings that characterised previous albums, in favour of a much more spontaneous ‘instant arranging’ approach in which any band member can instigate solos, small groupings or the next tune as and when they see fit. It lends the whole show a genuinely risky feel as a stumbling shuffle lurches into off-kilter swing or a melodramatically tongue-in-cheek free piano interlude takes off into a sprinting blues. Among all the mischief, there's some fine playing too: Mary Oliver's violin soars with a sonorously oriental tang, and Jorrit Dijkstra suggests a queasy cosmic event with his lyricon – a vintage analogue wind synthesizer from the 1970s. It's simultaneously serious and silly – and probably just how Lacy would have wanted it.
