CHICAGO — As the natives like to say, this city is associated with deep-dish pizza, Al Capone, Michael Jordan, Oprah Winfrey — and, of course, the blues. Chicago has often been called the home of the blues. Such locals as Muddy Waters, Buddy Guy, and Willie Dixon stand out as important influences on the Rolling Stones, Led Zeppelin, and so many other rock luminaries.

While blues clubs are declining nationally, they are still going strong in Chicago, which I confirmed on a recent pilgimage. The classic blues hit “Sweet Home Chicago’’ is still heard throughout the city.
