If you're a fan of Chess you're probably aware that there are a number of different versions out there and that Tim Rice changes his mind on a regular basis as to what the best approach is to the show.
This recording offers a great deal over and above the original cast recording. The story flows better, Someone Else's Story is a fabulous song and the majority of the good stuff is left well alone. Vocally it is solid but it doesn't have anything to set it apart dramatically from some of the other recordings.
What it doesn't do is offer a good base for any amateurs that are performing the show (in the UK). If you can find a copy of the Danish version of Chess then go with that in preference to this one. It has Someone Else's Story and it also has Soviet Machine and Merano - songs that are fundamental to the show for me.
If you're buying for the pleasure of listening then I'd advocate the original London cast recording over this but that's more personal preference than anything else.
But if you're looking for a template to help you when performing "Chess" hunt like mad for the Danish version (which is in English) of the show. It is a very good version of the show that is all but note for note with the score that you'll receive.
