I want some suggestions

One "modern" composer (in that he lived in the 20th century) is Bela Bartok...His music takes a little getting used to, but if you listen to it with an open mind, you might find yourself liking it, as I did...a favorite is his Concerto for Piano and Orchestra # 3, especially the charming, peaceful 2nd movement...check it out...

You might also want to check out Brazilian Composer Heitor Villa-Lobos, especially his Bachianas Brasileiras and Uirapuru...

Thanks for posting in this old thread, I'm still interested in new classical music!

I will check the two you mentioned.

I will advise the following :

Mozart : Big mass in C minor (Kyrie)
Ravel : Piano concerto in G (slow part)
Bach : Mass in B minor
Brahms : Symphony N°4
