Thanks for the nod, Pedro.
One could do a Melting Watchtowre blog or paper on this subject. There are far too many examples.
Yes, the Forbidden Planet score opened my mind to "space music" in 1956, no less. SPACE PIRATE RADIO wouldn't have existed without it. Also that theremin in Bernard Herrmann's "The Day The Earth Stood Still."
1951, no less. And, as Pedro noted, the mind expanding scores in "Journey To The Center Of The Earth,"
"Mysterious Island," "Jason And The Argonauts" & "Fahrenheit 451." "Twilight Zone" theme. "Citizen Kane."
more modern stuff: Can "Deep End." All of the Vangelis film scores, starting with "Apocalypse Of The Animals,"
"Le Fete Sauvage" which got reused in Peter Weirs "The Year Of Living Dangerously." "Blade Runner," "Bitter Moon" and "1492," besides the Oscar winning one.
Look how many prog musicians went into the soundtrack biz. It seems anyone who ever was a member of
Tangerine Dream did film. Good or bad.
Keith Emerson, Rick Wakeman, Colin Towns, "Full Circle" aka "The Haunting Of Julia."
Goblin is one of many Italians in film. Banco did at least one. And the school of Morricone is totally whacked out in the '60s & '70s. Bruno and Nicolai.
King Crimson "Larks Tongues" is in the first "Emmanuelle" film, interpreted by Francis Lai.
Klaus Schulze wasn't the only progressive artist to do "hardcore" films. A certain well known synth artist
told me privately that he had scored many of them under alias.
Christopher Gunning, "Goodbye Gemini." Irmin Schmidt's soundtracks.
Another early favourite, Paul McCartney's "The Family Way"
Good sounds make great pictures. Cheers, everyone!
