Since the Washington debut of Blue Heron in 2010, the Boston-based vocal ensemble dedicated to Renaissance music has been a group to watch. Their concerts this weekend on the free series of the National Gallery of Art are related to one of the group’s best recordings, devoted to the music of 15th-century composer Guillaume Dufay.
The museum has programmed the concert, focusing on music made for the Medici family during Dufay’s time in Florence, in conjunction with its new exhibit “Della Robbia: Sculpting with Color in Renaissance Florence.” One can hear this program at noon or 2 p.m. Sunday, in the resonant West Garden Court of the museum. Admission is free. nga.gov.
Igor Levit has won critical praise for his daring recordings and performances. The Russian-born pianist had to cancel his scheduled debut here a couple years ago, which Washington Performing Arts will finally present 2 p.m. Saturday at the UDC Theatre of the Arts. washingtonperformingarts.org; 202-785-9727.
