Probably not in terms of general aesthetics- yes in terms of technology, etc. From one project to the other, many other things changed- different performers, a lot of personal issues for Courtney, etc.
When I was involved in the project, everything was recorded in DSD. It was only transferred to Pro Tools after I left, which occurred before Courtney began her vocals. About 60-70% of the vocals on Celebrity Skin are from Courtney's guides which were done over the course of 2 days.
We spent months trying to get finished sounding vocals and it always felt as if something was missing. One day, while listening to a playback, it suddenly occurred that what we were missing had actually been there from the beginning. When we brought up Courtney's guides, it was really obvious. I comped them together with some of our later vocals for the finished versions.
