Query: Could be great but...

Who would have thought that someone could cram two of the greatest Russian orchestral works from this century onto one CD? While some reviews boast that this is a great orchestra under a great conductor one can hardly tell during the entire Shostakovich. The Prokofiev is so-so, but the recording is still desperately in need of digital remastering. Crackling and the woes of poor recording equipment prevent pleasurable listening to these great masterpieces. It is as if the producers simply made a CD out of an old and scratched record. (An event not entirely impossible.)
