Kenny Barron Trio Ronnie Scott's, London W1

The piano at Ronnie Scott's is a perfectly good concert grand, but when Kenny Barron sat at it last week it sounded different. It was as though black-and-white had suddenly turned into full colour.

The place was full. I should imagine that a fair number of those present were pianists, keen to discover whether Barron really is the complete jazz pianist that his recordings reveal. And he is. His tone is both crisp and rich, with beautifully defined lines and harmonies which melt and reshape in endlessly fascinating forms. It's no wonder his work is forever being anatomised, but the magic of the thing itself eludes analysis.

The trio also contains, in the person of Ben Riley, one of the greatest living jazz percussionists. In his playing the connection between jazz drumming and tap-dancing is delightfully apparent. Resourceful, witty, Riley touches the beat with feathery lightness, rarely uses the hi-hat cymbals, and even wears gloves to play. He follows Barron's every move with snake-like concentration and bonds perfectly with the excellent bassist, Kiyoshi Kitagawa.
