U2

Gladys Knight, George Clooney, Amy Grant, Tania León and U2 were all celebrated at the Kennedy Center, which annually honors a group of people for their artistic influences on American culture.

Four songs into the sold-out show, Bono experienced a "complete loss of voice." The singer suggested that standard smoke machines may have been the cause.

Multiple performances have been canceled over safety concerns, amid unrest prompted by the acquittal of a former police officer charged with first-degree murder in the fatal shooting of a black man.

The band that was playing in the Bataclan concert hall during the Paris terrorist attacks returned to perform with U2.
