Science Fiction and Fantasy often inspires music, often by rock and metal bands but also new age music and (I suppose) hip hop. Different writers have had differing opinions about the music they inspire.
Iron Maiden made a song called “To Tame A Land” which was based on Dune, but Frank Herbert dissed the band and heavy metal music in general pretty bad.
On the other hand, Michael Moorcock enthusiastically supports rock band versions of his material, helping Blue Oyster Cult with the song “Black Blade” and even jamming with BOC main man Eric Bloom on occasion.
One thing that I want to know is whether or not JRR Tolkien was aware of Led Zeppelin and what they did with his books, and what he thought about it.
Also, have other writers gone against bands that made music based on their books?
And Mercedes Lackey has released several CDs of songs from and/or based on her books, and other artists have produced more with her blessing. She was a filker well before she got any of her stories published, I believe.
Janis Ian isn’t a fan; she a pro. I processed her SFWA application; she qualified because she had some short stories published in Mike Resnick anthologies.
In a similar vein, Leslie Fish’s filk song, “Carmen Miranda’s Ghost is Haunting Space Station Three” inspired a collection of short stories with the same name.
Searching Wikipedia for low hanging fruit: SERIOUSLY? Universal Studios made them pay 25 grand because they got the idea from watching E.T.? Is that for real?
