From Steve Jablonsky:
Nice to hear from you. As you probably know the score is now up on iTunes. The physical CD situation has been more complicated. I finished the album weeks ago, but we didn't actually finalize it until a few days ago. Michael Bay is really happy with the score and he wanted to check out the album before it went out. As you might imagine, he's a busy dude. He's been flying all over the world promoting TF3, making it difficult to get approval. But I was happy that he wanted to be a part of the soundtrack and I did not want to release anything before he had his say. The record company tells me they need 4-6 weeks to get the album produced and into stores, which would put us into August at this point. A lot of discussion went into this, but the decision was made to wait on the physical CD, and release some kind of special edition alongside the blu-ray release (maybe autographed copies or other goodies, we don't know yet).
I know people are probably disappointed. Believe me I wish I could get physical CD's out there tomorrow. But it's just the way things went this time around. I can see why Paramount would rather not release a score CD almost 2 months after the movie release. To them it makes more sense to do something special around the blu-ray/DVD. I understand that.
So anyone interested in a CD should rest assured that it WILL happen. It just won't happen until later in the year unfortunately.
These big movies are so complex sometimes!! I hope you've been well!
