The festival’s most brilliant non-headlining performance was delivered by mid-career artist Brittany Howard, 36, who reunited with Alabama Shakes after a seven-year hiatus. At Harriet Island, the happy-to-be-here singer showed the world that she’s a world-class vocalist of deep emotion and Etta Jamesian drama.

If opening day is any indication of what the rest of the weekend will hold, the success of last year’s inaugural festival was no mere beginner’s luck.

The announcement from festival organizers came shortly after 10 p.m., saying: "Due to approaching weather and nearby lightning, tonight’s show has ended early. Please exit the festival grounds promptly and follow guidance from festival staff and local officials."
