Sara Bareilles has been blessing us with incredible music lately, and we can't get enough. After dropping her new single "Armor [1]" last week, the singer is back with a stunning Hamilton [2] performance. As part of Lin-Manuel Miranda [3]'s "Hamildrops" series, Bareilles had the honor of recording an unreleased song from the musical titled, "Theodosia Reprise." "We cut this Act Two moment between Aaron Burr and his daughter Off-Broadway," Miranda said of the ballad on Twitter [4]. Between the heartfelt lyrics and Bareilles's angelic voice, it's hard not to get chills. See the gorgeous performance above!
