In reply to:
think I'll go with Black Tie White Noise.
That's a good call, I forgot that one in my list, and avoids the trap of nominating an album just because it's a favourite (for reasons other than the production). Production is probably the best thing about BTWN, and it's maybe the one example of a very "cluttered" production that worked well. Also maybe the best blend of the synthetic and the traditional in Bowie's catalogue.
I'll stick with Low as best though, purely because of its influence and shocking originality. Sadly, as great as the BTWN production is, it didn't influence much that came after it. 90s music would probably have been a lot better had it, but as it was, BTWN marked the end of an era (one in which electronic and acoustic instruments were seen as complementary rather than competing, and brass was good) rather than the start of one.
