These recordings have been issued before by Decca, but this 2007 two-disc joint reissue from Vocalion has been remastered and, apparently, as I have no direct comparison, sounds superior. Regardless, these recordings date from 1977 and 1978 -- the pinnacle of the analog era -- and were made in Decca's Phase 4 process. They are astoundingly clear and rich in sound.
The two scores are justifiably famous, having all but invented the "Hollywood epic" sound, massive and majestic. They are pillars of craftsmanship, but, and I would argue this is the case for 99% of all film music, I would also say they lack depth equivalent to their 2+ hour lengths -- they are to overwhelm, to awe, to beautify, but divorced from their filmic context I find that they outstay their welcome. These albums of suites, at just over 40 minutes each, are at an ideal length to appreciate the scope of Rozsa's achievements without being bludgeoned into stupefaction. All of the essential cues, from the rousing marches to the heavenly choruses, are included.
Obviously, if you are a Rozsa completionist die-hard and you absolutely must possess each and every second of music written for these pictures including unused alternates, these discs will not satisfy. But if you are simply an admirer of finely crafted orchestral music, and especially if you are an audiophile, Rozsa's recordings with the Royal and National Philharmonic Orchestras are highly, highly recommended.
