The reviewer who called this music "boring" isn't listening hard enough. It's a beautifully intense piece of music that rewards the listener with each listening. Riccardo Chailly isn't really known for his Tchaikovsky interpretations, but this is a great reading with excellent playing from the Royal Concertgebouw and audio quality.
Unfortunately, like many recordings, this one is sadly out-of-print, but if you can find one used and in good shape for a good price, it would be worth it. "Manfred Symphony" is seldom recorded. I own many different versions: Jurowski, Pletnev, Petrenko, Jansons, and Rostropovich. I wish Bernstein had recorded this symphony as he would have really brought it alive, but this is a good performance by any standard and worth acquiring.
