Indeed, there has been quite a bit of negativity here about the score, but it has also been received positively by critics such as this excerpt from the LA Times review:
"The music, which is nearly continuous, provides a magic carpet of orchestral strings upon which the production floats at will. Musical director, conductor and keyboardist Kimberly Grigsby draws out a sumptuous sound from her orchestra. And every time Soo opens her mouth to sing, the stars in Paris' night sky shine brighter.
The songs by Messé and Tysen encompass a wide variety of moods and styles. “Goodbye, Amélie,” an Elton John parody/homage performed by Randy Blair in souped-up Crocodile Rockish garb, is the jaunty showstopper. “Thin Air,” a dreamy ballad for Nino (a dashingly nerdy Adam Chanler-Berat), harmoniously escalates the romantic chase between this solitary artist and the fey young woman who keeps leaving clues for him to follow."
I have not seen the show as yet but do have tickets to see it in a few weeks and I'm looking forward to it.
