please recommend me some complex or seemingly chaotic music

Buying a book, though, is getting advice. 

I'm glad you had a good experience.  Others are different.  However, when someone asks for advice, I'll try to give the best I can.

Books normally don't give you "advice", they give you information. An information what is regarded high in the musical world and how things are. This is something differant than advice.

Lots of instruments, singers if possible, going in all directions but still working together to form a solid coherent piece of music a la the last two minutes of allegro from Beethoven's 9th.

I am very new to classical music but I really enjoy that part in particular.

Thanks

I  recommend listening to representative works by Eliot Carter.  Brilliasnt but "difficult" composer. One of my favorites is his "Variations for Orchestra", a very complex piece commissioned by the Louisville Orchestra during the 1950's. Very involved thematic and rythmic development. Perhaps Carter was mentioned in a previous post.

If the original poster is looking for something complex in the manner of the close of Beethoven's 9th, then he or she is not looking for Carter.   Probably the close of Mahler's 5th would satisfy (although you have to sit through an awful lot to get through to the final movement coda).
