Never heard of Hazel Scott? Nor I. Happily, the marketing department of the New World Symphony has done some homework. “During the summer of 1950, Hazel Scott was one of the most famous women in the world,” the season announcement informs us. “The glamorous Trinidad-born pianist had already conquered Hollywood and starred in movies alongside Lena Horne and Mae West. Now, her namesake TV show was beamed into living rooms across America three times a week and her way of ‘jazzing the classics’ was adored by audiences at both Café Society and Carnegie Hall. Refusing to play in segregated rooms and making history as the first Black woman to host her own TV show, Hazel Scott was a trailblazer who changed hearts and minds with her music.” A four-concert minifestival places Scott in the company of lately more familiar Black composers from the transitional period between the Harlem Renaissance and the Civil Rights Movement: William Grant Still, Julia Perry, and William Dawson. Jeri Lynne Johnson conducts; the pianist Michelle Cann and the vocalist Brianna Hunter are prominently featured. —Matthew Gurewitsch
