I see what you're getting at. If I were to get technical about it, I would put it under "D" for Dave Rawlings Machine like I would put Pink Floyd under "P", but for ease in finding it, I'd probably put with the other Dave Rawlings records (under "R" I assume?).
I've seen record stores arrange things differently from one to the next. They often group artists that were in a band together. The one I was at yesterday had David Gilmour, Roger Waters, and Pink Floyd altogether for example. The one I go to most often does the same thing, for example all of the John, Paul, George, Ringo, Wings, John & Yoko, etc. records are all right next to the Beatles, under a separator that says "Solo Records".
