Idina, one of the best voices of recent Broadway history, as well as one of my girl crushes (hey, I fall for a pretty face and great voice!), launched a solo career a while back, and has put out some great albums. This particular one is on her live album, and it's just incredible. At the beginning, you hear her talking about Jonathon Larson, and this being her favorite song from the show. I mean, it is basically the entire theme of the show.
She takes this one pretty slow, and just kind of lets the words since out. So nice.
