I dunno, I have the concept CD, certainly love it, but I feel like my favorite at least from listening to it in a CD store is the "soundtrack" of the DVD made in like 2003. The voices are just fantastic.
Also, nothing can compare to Michael Ball's "Gesthmane" from Andrew Lloyd Webber's Royal Albert Hall Celebrtation. Really wish I had that version of the song...
"If there was a Mount Rushmore for Broadway scores, "West Side Story" would be front and center. It snaps, it crackles it pops! It surges with a roar, its energy and sheer life undiminished by the years" - NYPost reviewer Elisabeth Vincentelli
