It was going to be an important year for Angélique Kidjo. In March, a few months after earning her fourth Grammy Award (for her Celia Cruz tribute album, Celia), the singer had planned to celebrate her own 60th birthday — along with the 60th anniversary of independence of her native Benin — with a special performance at New York City’s Carnegie Hall featuring everyone from Nigerian Afropop star Yemi Alade to Brittany Howard of Alabama Shakes.Of course, due to the coronavirus pandemic, those plans changed, and the March 14 concert was cancelled just days ahead of time.
