Allan Holdsworth Trio, The Ferry, Glasgow

Star rating: **** As a guitarist, Allan Holdsworth's fingers understandably grab the attention. There's his left hand with its improbable reach and spidery command of the whole fretboard, and a right that can play hide the plectrum while picking with thumb and three digits. Just as fascinating, though, is Holdsworth's left eyebrow. This is what he uses, with a slight arching, to acknowledge his audience's stupefaction. It's not aloofness, more that the super-self-critical Holdsworth seems to be saying: "Well, you might have thought that was okay but I was hoping for something better."
