^ That is very true regarding the "second act". If you notice, disc one has a perfect balance of themes - recurring or not - because it's the phase featuring what in musical theatre jargon are known as "I am" and "I want" songs, i.e. where characters and their motivations are introduced and lead to intersection. The second disc seems to be incapable to fully develope its many themes and ideas for two reasons, IMO: 1) It's rushed, probably with live show timing in mind and generally because it's much easier to establish a plot than leading it to an effective and consistent conclusion, 2) "second acts" are usually the dynamic/clash phase of a show, in which the composer almost always needs collective singing numbers in order to joust both the plot and the musical themes; the singer in this case - excellent in his many interpretations - can only sing one character at the time, and this limitation greatly influences songwriting and the management of themes in such a dynamic phase. I hope I've managed to make a bit of sense, because I'm brutally synthetising concepts deserving longer and clearer prose.
