Like Rent it's pretty groundbreaking...like Avenue Q it's a bit explicit .... It's got substance...it's got great music and it deals with some very intense issues.
It can be sweetly poignant
It can be ....rock hard (yes...that was intentional)
If you've never heard the music give it a listen ...if it comes to your town...by all means buy a ticket! You'll enjoy it it will make you think.
