There is so much that is good here, it's hard to know where to start! 1st, the price: for a small sum you can get this 4 CD set and the stand-alone disc with "The Spider's feast" and the Padmavati suites. 2nd, the sound is stellar giving details missed in other recordings. 3rd, the performances and interpretations are sensational! 4th, the diversity offered: the 5 CDs contain the symphonies PLUS eleven other orchestral works from different periods of Roussel's career. As to the composer, I'll only say that anyone who wants to know 20th C. music should consider experiencing his work. This is the perfect way to start. Anyone who has some of the other great recordings like Dutoit's or Jurowski's or Martinon's will still enjoy hearing this great set.
