The 11th season of NBC's The Voice kicked off this Sunday, August 21, with an all-star cast of coaches that includes alums Adam Levine and Blake Shelton, and newcomers Miley Cyrus and Alicia Keys. At the end of the big post-Olympics premiere episode, the quartet teamed up for a smashing rendition of Aerosmith's "Dream On." Keys fittingly handled the piano, while Levine played guitar. The four took turns at the microphone, harmonizing in pairs before coming together for the finale. After they finished, the screen went black and read, "In loving memory of our friend Christina Grimmie." Grimmie was a former Voice contestant who was tragically murdered earlier this year. Watch the touching tribute below.
