For once, the word "unique" really does apply in the case of this partnership. They have been crossing genres for the past 40 years – cabaret, musical theatre, opera, brass bands, oratorio and every imaginable sort of jazz ensemble. This time, the subject is nothing less than the fall of man, with music by Mike for saxophone quartet and drums, and words written and declaimed, rather than sung, by Kate. The music is by no means easy listening, but full of surprises – spiky and tender, warm and ice cold. There's some great playing, too, especially by alto saxophonist Chris Biscoe.
