Listening to The Symphonic Fantasy on BACH by Eugen Suchon.
This is one of the most horrific, turbulent and eerie works I have ever heard.
Put away all sharp objects before listening..this is very rough sledding, Kabelec's angriest moments come to mind. Be advised that the clip is over attenuated and should be played at the lowest 2 notches of the volume control at this site:
