This is a reissue of recordings conducted by Copland himself that are totally definitive and, to my mind, superior to the recordings by Bernstein that are generally considered to be the best. The composer has a broader, grander vision of these works, taking them at a slower and more majestic pace than Bernstein and others. In his hands this is great classical music, not just upscale cowboy music. The sound quality is phenomenal for the most part as well, the engineers must have performed miracles because the recordings with the LSO sound better than almost any modern digital recording. Highly recommended.
