Some jazz musicians can’t help but devote themselves to a specific idiom or era. This is usually a necessity borne out of love and can thereby generate a heartfelt sincerity often absent from the self-consciously cutting-edge. Though nostalgia and romanticism for the ‘Golden Era’ of jazz - usually encased between the carefree 1920s and the moon landings - undoubtedly colour this view, it remains true that many of our finest instrumentalists, singers and fans alike have preferred to peer round the ultra-modern corner, back home to the past.
