Go deep with Vladimir Horowitz, Beatrice Long, Glenn Gould and more performing the utterly out-of-this world keyboard sonatas of Domenico Scarlatti. Two hours of compelling classical will also feature a piece from Lera Auerbach and a woodwind quintet from Jean Francaix and more. Catch it all tonight from 8 to 10 p.m. or stream it on demand right here.
