Thx for the review, @Matt Hough . This is one I'll pick up eventually.
I find Sondheim to be a rather pretentious individual and listening to him (and his sycophants) talk about himself (and him) for a couple hours could be mind-numbing for me. But I also recognize and acknowledge his genius. So I would be interested in hearing about his creative process. I would also be interested in learning about his choices in terms of melody construction. He seems to use many of the same progressions and such in his composition. And at least he acknowledges and appreciates those (like OH II) who came before him.
