The theory is this: I think that if someone is NOT classically trained, he might be more inclined to like something "a little advanced" rather than someone who is classically trained and thus too used to the usual stuff.
So someone who enjoys the likes of Bach, Beethoven, Chopin or other might have issues with the next couple of videos, or even feel the music is disturbing (as I've been told), while someone who is not into classical music at all, might not find anything irritating to the videos and might enjoy them, outside any prejudice.
A work by Barnaby Hollington for String Quartet. Recorded live (and a great recording it is).
A series of short works of mine for solo piano, recorded with the Garritan Steinway (*ahemsamples*)...
They are vastly different, in my opinion, but then again I'm quite biased!
In anyway: Enjoy...
