There's an Ennio Morricone soundtrack for every occasion, and Halloween is no exception. A few years ago I put my stereo in my front window and played the Gothic Dramas soundtrack for the trick-or-treaters and received compliments from all manner of super-heroes, monsters, football players, angels, devils, and their parents. The recordings are from a 1970s Italian television series, but it was only released in the 1990s by DRG Movies. Check it out. And from there you might look into his soundtracks to three Dario Argento horror flicks lovingly collected on An Ennio Morricone/Dario Argento Trilogy again by the fine folks at DRG. And DRG also released a 2-CD compilation called The Thriller Collection if you want yet more spine-tingling Morricone. And of course he scored Exorcist II: The Heretic. And don't forget Gli Occhi Freddi Della Paura/The Cold Eyes of Fear (the lone Morricone score performed by his free jazz ensemble Il Gruppo di Improvvisazione Nuova Consonanza). I could go on, but you get the idea.
What will be the soundtrack to your Halloween?
