Well, I don’t know nearly enough about Bach to speculate on this. When I think “Bach” I think about something like “the beauty of mathematics” because as I understand it he had a genius for structure, interlocking parts, counterpoint, and so on. The only thing of Bach’s I know decently well is Glenn Gould’s first recording of The Goldberg Variations.
How Bach might tie into Tomboy I cannot say, but my sense is that Lennox operates on a much more intuitive level and doesn’t have much of a “deep structure” kind of thing going on. But certainly the connection between reverb and liturgical music is an interesting one, and I’ll bet there is some good writing out there about that.
