Here are three brilliant acoustic guitarists. If you have difficulty telling who's playing what, that's not surprising. Bucky (born 1926) taught the other two, his son John Pizzarelli (1960) and Ed Laub (1952). And they all play seven-string guitars, so even the bass line tends to get swapped around. It's a marvellous, plangent sound, so intimately recorded that you can hear the fingers moving on the strings. The programme consists mainly of American classics – Avalon and If I Had You – that never seem to lose their shine. My favourite is Bix Beiderbecke's In the Dark.
