CD Collections of film music are largely covers collections, which are oftentimes disappointing, mostly due to the inability of some synthesizer guru to capture the complexity of the inherent dynamics of soundtrack music. Even if a genuine orchestra takes up the challenge, the result is more often than not shallow and uninspiring.
This collection, however, was in many ways a pleasant surprise. Not only does the Prague Philharmonic manage to produce the emotional depth, but they also add various instruments where required - from harmonicas to boys choirs, from organ to electric guitar (where needed). Some bits are real goosebumps, like their rendition of the Godfather theme "Speak softly, love". Even the 20st Centruy fox theme sparkles close to the original. There's scores included from 1939 up to 2005.
If you're into film music but do not want to painfully collect a 100 original soundtrack CD's, by all means get this one instead.
