My vote would also be for Alan Parsons ProjectFall of the House of Usher first appeared on a tribute to Edgar Allen Poe called "Tales of mystery and Imagination" The piece was 15 minutes long an consisted of 5 movements
(i) Prelude
(ii)Arrival
(iii)Intermezzo(iv)Pavane(v)FallThe first time I heard it and every time thereafter it sent chills up my spine.
Truly Poe put to music.
