Instead, her brass duo complemented her DJ/electro drummer and the all-smiling Kelis magnificently merged old-style soul with new technology. She started, finished and marked the evening’s halfway point with snippets of the evergreen Feeling Good, which recalled Nina Simone’s version and covered Labi Siffre’s Bless The Telephone with gorgeous restraint. Yet she transformed Milkshake into a speeded-up electro clatterfest; thundered her way through 4th of July (Fireworks) and suggested Minnie Riperton’s classic Les Fleurs on the uplifting Acapella. Best of all, old and new met to spectacular effect on Biscuits N’ Gravy, which began as a simple ballad and ended as a kitchen-sink spectacular.
