And as for Spring Awakening...
It's a hard show to describe in just a few sentences, so I'm not even going to bother.  For now, I shall just say that I liked it.  A lot.  Great cast.  Great band.  Simple, but very effective lighting.  Good sound design.  Etc., etc., etc.
It's definitely not a show for everyone, and the way I'd advise anyone who's thinking about seeing the show would be to show them the song titles.  If they don't flinch at "You're F*cked", then they should like the show.  Or at least give it a fair chance.
And, yes, they do sing with microphones.  And quite well too.
