When I play with the song's time signature / measure, I usually do so in such a way so that it still maps in some consistent way to the original measure: I might just shift every measure over a couple of beats so that my measure run from beats 3 through 2 of the originals, or I might slow down the original but cram in 3 measures for every two, etc. That way, any melodic motif I come up with can actually be repeated, because the notes will fall in an unusual but consistent way within the original score that determines each note; it also means that I can map to some alteration of the original chord progression, rather than giving that up to randomness. That's what I did with my latest one, Chariots of Fire; that little repeating melodic bit on the violin is only possible by shifting the measures that way.
If I try just leaving the original behind completely and not mapping to it in any consistent way, it's more difficult to establish some sort of continuity, etc. But that's just my way of doing it; I believe Chicken is interested in going a bit further away from the original.
Also: Kid A, your newest recording is wonderful; once again you've teased out a very nice pattern from the chord arpeggio, and the percussion is incredible. Regarding Videotape, I do greatly enjoy the Basement version (that entire concert is fantastic), and it does make me more amenable to the album cut the more I listen to it... I still feel like something was lost from the live version, particularly where I want it to pick up a bit at the end instead of just trailing off. But I look forward to seeing you try something with it--those rolls would be pretty tough in this game.
(By the way, Kid A, you're supposed to pick which version of that song I keep--the one with the drum set or the one with just the big bass drum. Probably the latter is better... but I might try a third variation eventually.)
