Ennio Morricone's most amazing soundtracks would not be the same without her. If there's a voice which best encapsulates the desperate beauty of giallo soundtracks, it is Edda Dell'Orso's.
Maybe it's better not to say much about Edda. Her voice is everything. Nothing compares to her delicate and beautiful wordless vocals which are able to turn any melody into a moment of grace.
She sometimes reminds me of Elisabeth Fraser, from early-80's bat-cave band Cocteau Twins : both share this originality of singing without words in a pure, almost virginal way.
Their voices manage to convey superior beauty and infinite sadness at the same time.
What would be the most important moments in gialli if they were not insufflated by these highly emotional and delicate scores?
In gialli, music always leads images. Not the other way around.
A great compilation of Edda Dell'Orso's work can be found on Movie Grooves, here.
