Like hundreds of others out for this sunny evening, I brought along a short chair and light supper to enjoy on the lawn. Headlining for the second night in a row were consummate musicians in the blues tradition, Keb Mo and Taj Mahal. Contrary to the impression these side-by-side photos might give, they did not perform together, but had separate sets, with Keb opening. Their performances were big crowd pleasers.
