Classical composers, symphonies


I thought I would reach out to Audiogon fans of classical music for some help, having seen the numerous posts in the afficionados thread.

I am a big fan of large orchestral works like symphonies, particularly of Rachmaninoff, Tchaikovsky, V Williams, Wagner, Mahler, Brahms, and Bruckner(Romantic).

If you could recommend one or more additional composers to explore that are similar, who would you recommend?

Thanks in advance.

It's been recommended already by jtuba but the Schumann symphonies
are very underplayed  for as good as they are !
Thanks for the suggestions.

Something about Sibelius turned me away earlier in life, I will have to revisit 
Will listen to Nielson, Schuman, and Paganini more

Looking forward to some that I have never heard of, in craig159 post

I still find it hard to beat rachmaninov or Tchaikovsky 

I am not a big fan of Piano concertos for some reason , except maybe Rachmaninoff 's. 

Thanks again,

Will be hitting you tube or Pandora now😊
You mentioned that your not a fan of piano concerti. But I recommend you sample the Beethoven concertos, they are unlike any other. They are written in sonata form like symphonies and the orchestra plays a greater role, they are not simply accompanying the soloist.
Re Sibelius, Symphony #2 is a favorite of most coming new to this music. It is more  'romantic' than most of his music and it is usually played 'big'. His first symphony is more like some of Tchaikovsky's symphonies in its style (however it is music unique to Sibelius). His later symphonies are more modern in style, albeit still very accessible. FWIW, IMHO, not withstanding these observations I think the best of Sibelius' symphonic music  is  found in Symphonies #4, 5, and 6. These works are leaning more towards the modern a bit but are still very tonal and accessible. Symphony #4 is probably best left for last but I found it my favorite once I had absorbed it.
