Pianist Simone Dinnerstein
's 2007 recording of Bach's "Goldberg Variations" became an unlikely hit, topping the Billboard classical charts, reaching No. 3 on the Amazon charts, and for a time, leading iTunes in downloads. This summer she releases her follow-up CD, "The Berlin Concert," and tonight she performs at Le Poisson Rouge, the new concert venue in Greenwich Village. She performs live for us today in the studio.
