Sibelius - Symphony No 4

I am working through Sibelius's symphonies at a rate of about one a month (though I'm a bit behind) and this is the halfway point of the cycle. I had forgotten how good the Fourth was, with the exception of the bleak beauty of opening of the first movement. I really enjoyed it all (or did I? It's too gloomy a work to talk about enjoying, exactly). Things I had forgotten or hadn't noticed before: the similarity between the start of the scherzo (the 2nd movement) and the final movement of the Third Symphony. The abrupt and anticlimatic way the whole thing ends (the 2nd movement too). A lot of it is amazingly dissonant, for Sibelius.
