We arrive at the sun-kissed rooftop foyer of a BKC five-star to meet the four international artistes playing at the Mahindra Blues Festival this year. Coco Montoya, Layla Zoe, John Mayall and Walter "Wolfman" Washington are seated in one line at four different tables, interacting with the media ahead of their weekend performances. Zoe aside, all the other three were brought up in an analogue era that is as far removed from today's generation as a dusty vinyl is from digitally downloaded music. Montoya, at 66, is the youngest of the lot. Wolfman is 74 years old, and Mayall is an entire decade older than him.
