I wouldn't say I was a fan, but it was the first kind of literature I became genuinely interested in, and that early enthusiasm has never really gone away. The problem is that when I started to become reasonably well read in a more general sense it was easy to see that so much SF is frustratingly badly written, particularly when it consists of a thought-proviking basic premise or concept for which plot and characters are perfunctorily attached just to make a novel out of it.

As for whatever the connections might be between classical music and SF, you'll no doubt be aware that there are very many references to classical music in the writings of Philip K Dick (and one entire short story, "The Preserving Machine", based around the idea of musical scores being converted into living organisms) - however, this isn't a feature of any of the films which have so far been based on his work.

Perhaps you would find the works of Stanislaus Lem more satisfying?

Lem certainly stands above most of the field. The SF novel I recently enjoyed most was Justina Robson's Natural History, although I haven't liked her other books much.

Other SF operas: Tod Machover's VALIS, Karl-Birger Blomdahl's Aniara, Lorin Maazel's vanity exercise 1984 perhaps... and, stretching a point, Stockhausen's LICHT. Chris Dench was for many years planning an opers based on Lem's Solaris but I believe there was some complication regarding the rights.

I have read very few sci-fi books, but I think I can state fairly confidently that I have now fully recovered from knowing that there will be no more new Star Trek series!

I read all Terry Pratchett's books, but I do not count that as sci-fi.

I think you could stretch a point and find two Janacek operas in the realm of "sci-fi"... 

• THE ADVENTURES OF MR BROUCEK (he does fly to the Moon and back, after all - I see this as being in the same kind of "humorous sci-fi" genre as the Lumiere-Bros "First Men In The Moon" etc
• THE MAKROPOULOS FORMULA - this is more clearly "science fiction", complete with time-travel, an immortal being, a magic formula, and inexplicable circumstances.

Ligeti's LE GRAND MACABRE has elements of sci-fi in it (a malign force intent on destroying the whole world),  and there's a lot that's very, very unnatural in Prokofiev's THE FIERY ANGEL, which has necromancy as its central theme (and the strange secrets procured by Jakob Glock)

Stretching the point still further, Stephen Storace's THE HAUNTED TOWER (1789) has elements of necromancy too, and the confrontation with the ghost ("Spirit Of My Sainted Sire!") is one of the earliest openly "supernatural" scenes in opera?

Goodness gracious, I feel we've kicked the R3MB Opera Quiz back into play!?  Where's Parsifal....?

SusanDoris - nice to find another Pratchet fan here - I'd refer to his books as Fantasy, rather than sci-fi.

Hmm, judging by this thread, it looks mostly like fans of Joachim Raff also like sci-fi!

I've fairly recently read 5 of H.G. Wells books and I found "Journey to the Centre of the Earth" better than "War of the Worlds", "The Island of Dr.Moreau", "First men in the Moon" and "The Time Machine"...I've also read 2001 a few times and only once did it actually make sense!  At the moment I'm on musical reading mode and reading a volume of musical criticism by Hanslick.

Any operas etc with John Wyndham subjects ? (Well, we're talking semi-science fiction). What about the Chysalids ? Could be topical after all.
