Audra McDonald wowed an audience of more than 18 million viewers on the live, televised broadcast of The Sound of Music on NBC last Thursday, portraying the Mother Abbess to great critical acclaim. McDonald "has been pretty much unanimously appointed the show-stealer of the night," says TIME. The Christian Science Monitor says "McDonald was a majestic Mother Abbess." The Los Angeles Times says: "The golden pipes of McDonald, playing the Rev. Mother, opened the broadcast, but her memorable scene came later, singing 'Climb Ev'ry Mountain,' one of Rodgers and Hammerstein's most enduring numbers from their 1959 Broadway musical." Watch the performance here. And hear her take on "Edelweiss" on her new album, Go Back Home.
