So many people who made invaluable contributions to classical music were underappreciated in their time, or have been nearly lost to history. That’s why KDFC is starting Open Ears, a series of stories about composers, musicians and conductors who deserve more recognition, starting with a look at the life of singer Marian Anderson, conductor Calvin Simmons, composer Florence B. Price, and influential pianist, singer, and teacher Amanda Ira Aldridge.
