I don't have time to do full reviews of what I've seen so far, but here are some brief thoughts.
Therapy Rocks: Very good book, hard rocking score a fantastic cast (Rachael Stern, Dee Roscoli, Allie Schulz, Josh Davis and Adam Halpin). The staging of the performances by the entire cast remind me of Spring Awakening).
Roofless (reading): One of the most original ideas I have ever seen, a gangsta-themed graphic novel set to a Hip-Hop score. The entire cast was good, but Alan H. Green was insane!
Show Choir: I really liked it. A ton of subtle theater references, a few pop culture references that hit you right over the head (Kayne!), and an extremely talented cast.
Bloodties: Great score, emotionally powerful. The effect is intensified by the fact that the person who lived the story (Ned Massey) is playing it out on stage with four other very skilled actors.
Nighttime Traffic: I'm sorry to say that this show made no sense to me. It started nowhere and went nowhere.
Without You: WOW! Anthony Rapp is beyond amazing! He pours his heart and soul into that show. It is the most deeply personal show I have ever seen, and the best musical I have seen anywhere in 2010 so far.
I'm seeing Without You again today (the 2nd of 3 times) and opening night of Frog Kiss.
Drench yourself in words unspoken. Live your life with arms wide open. Today is where your book begins. The rest is still unwritten.
