I feel like a broken record on this board since I type this word in almost every thread, but...
Rent. I love it and I really don't see anything in the near future passing it as my favorite.
I'm also going to follow the trend and say LB is another of my loves. I remember waiting for the recording for months and months after I saw the first "Road To Broadway" video on broadway.com, and it didn't disappoint. :)
"It means nothing to come and sit in a theater night after night and immerse yourself in fantasy, only then to walk out the door and be unchanged in reality. This show will live on in our hearts. But where it truly must survive is in our actions, our compassion and our generousity of spirit towards one another." - Adam Pascal on the closing of RENT
