What classical could be considered prog?

[RogorMortis]

If you look thrugh my collection of classic cds you will discover that 95% of the music is written after 1900.

The 5% are basically music written in the latter half of the 19th century plus composers like Bach and Beethoven.

It is very difficult to define music as prog - because at the time of its publication the music was very prog but now perhaps considered as rokko, romantic or rubbish.
