Dvořák got the idea for his Seventh Symphony at a Prague railway station, but it grew into one of his most personal (and dramatic) masterpieces. And in Black History Month, conductor Christian Reif celebrates a neglected classic by the American composer Julia Perry: you’ll wonder why we don’t hear it more often.
