Booth is the great communicator. Whatever style he plays, and new album 44 covers everything from the rock-grooved ‘Blues in the Square’, to the group improv of ’Tale of Tetra’, Booth’s writing, arrangements and performance seduce you with their immediacy, control of dynamics and inner dramas.

Mind you, he doesn’t make it easy for himself. For his 33rd birthday, Booth played around with threes on Trilateral. So now he’s 44, he’s playing around with double quartets. (Lord help him on his 88th). Flo Moore related to this correspondent that it was some challenge for her electric bass to meld yet contrast with Whitford’s rich wooden tones, but it works a treat: each can solo, Whitford resonantly on ‘Four Candles’, Moore melodically on ‘Quad Rant’ (you're getting the foursomes now, right?), but it’s their rhythmic interplay that locks down the release four- square.

And it’s another of Booth’s communication skills that he can draft in such different amalgams of talent, and encourage them to play so coherently together. He mixes up old pals like Bain, with bright young things like Moore, but it’s the young in years but rich in delivery Alexandra Ridout (another Aylesbury alumni) who steals the show. Her trumpet has a sharp but never pushy presence which delivers in the briefest of phrases, doing her own thing not Miles’ on the inevitable Davis cover, ‘Four’. Forthright, forthcoming, there’s a fortune of talent here. Ok, ok, I’ll stop right there.
