Difficult to focus on 10 -- I must have left out the most important pieces! Cheers

Eldragon, I agree on Mozart. Mozart, Requiem; take any Bohm, Klemperer, even the old Karajan.
On taste, I beg to disagree slightly: Edd states he's new to the gendre so rather than "personal taste" I think that "impressive", "likely to hook", "representative" & similar are more appropriate words. Cheers
