I agree totally about Stravinski's conducting. I heard numerous performances of The Rite, and the weakest, most limpwristed and uninteresting was conducted by him. Composers (except usually film composers who HAVE to be good conductors - or at least did in the past) are the worst conductors of their music because they are thinking about all the clever little doohickeys and filagrees they lovingly put into their music ("just listen to this! isn't that great! Wow!" ) instead of the overall thrust of the music.
Yeah, Fahrenheit 451 is another great score by Herrmann. The recent McNeely recording is excellent, but on that particular score Herrmann's own conducting of the suite is the best. It was on a London records release from the 70s. I have the old LP, but it is probably on CD now. The finale of that with harps and strings is so beautiful, like Ravel but not stolen, and the lyrical quality is brought out by Herrmann more than any other conductor, completely contradicting the people who say he never wrote melodies.
That Herrmann symphony is very strange. I have not even been able to listen to all of it and so I should reserve judgement, but it seemed uninspired and vague. Though maybe that's wrong. It is nothing like his film music, which might be a recommendation for other film composers, but not for Herrmann. For example, the later works like Souvenirs de voyage are very much in keeping with his film style but perfect chamber works in their own right.
