As if I hadn't yet had enough, my friend Elena and I made our way over to a packed Music Hall of Williamsburg after the Pool on Sunday for the free aftershow with Celebration. The Baltimore trio added a supplement of brass and percussion players, but all eyes were on the bewitching Katrina Ford, who sang in a dark mezzo crossed with a banshee wail. Amazingly, they saved their most overpowering number for the encore, something Ford said they were "just trying out." Shit, you sure couldn't tell from where I was standing.
