February 11, 2021 While Massachusetts businesses and cultural institutions remain partially open amid reopening rollbacks, many residents are continuing to stay home due to the coronavirus pandemic amid new orders and advisories from Gov. Charlie Baker and Boston Mayor Marty Walsh. With that in mind, this week’s BosTen offers a mix of in-person and virtual things to do this weekend. Have an idea about what we should cover? Leave us a comment on this article or in the BosTen Facebook group, or email us at [email protected]. This Thursday, GBH will host a lunchtime chat about Black contralto Marian Anderson and her historic 1939 performance in front of the Lincoln Memorial on Easter Sunday. “American Experience” Executive Producer Cameo George and Duke University historian Adriane Lentz-Smith will join host Sue O’Connell as they discuss Anderson’s legacy, which is the subject of GBH’s upcoming film “Voice of Freedom.” The free talk will stream live at noon on GBH’s Facebook and YouTube channels.
