I wonder if this is the song I learned about in a master class with a british producer. He mentioned a song that was specifically detuned during mixdown by varispeeding the recorder ever so slightly so that the song was in a different pitch by the end of it. I don't have the notebook on hand so I can't remember the name of the song but it does sound similar don't you think? If not, there is another song out there that is recorded that way on purpose. Now I'm curious what song that was that we discussed in class.
