A little fact that no one will really care about, but I feel strangely compelled to post is that there is only one set of sounds on Endtroducing that was recorded specifically for the album. The female vocals in Mutual Slump were recorded for that track specifically, though Shadow chooses not divulge who is the owner of that voice. This goes along with DJ Shadow's general philosophy of non-disclosure when it comes to the sources of his samples.
