Not sure the term "dub" ever actually referred to the process of overdubbing (ie: disengaging the erase head on old tape decks, which usually degenerated the underlying sound quite a bit, and irreversibly changed the recording) I always thought the evolution of the term came more from "dub" in the sense of "making a copy." Not sure about international usage, but American musicians often will say "dub me off a copy," and we refer to dual cassette decks as "dubbing decks."
Anyway, splitting hairs really.
Interesting tidbit about
The Lamb Lies Down, always one of my favourite albums. (I suppose any time you let Eno into the studio, something is bound to start humming)
As to your comment about remixing being wimpish, all I can say is I'm generally not a huge fan of the remix, unless they are exceptional, and some
few are. In the main, I don't understand the glamour of the whole Dj-ing remixing beat-merging thing really. There's enough NEW MUSIC waiting to be made to last for all eternity without needing to re-hash, re-vamp and sub-mix what's been done.
Splitting hairs again.
