This high frequency tone shows up in a lot of albums, due to the presence of CRTs in old recording studios. Pink Floyd's "Us and them",  Radiohead's "All I Need from In Rainbows", and even the interstellar soundtrack, to name a few. In the behind the scenes footage of the recording process, you will see a crt TV next to Hans Zimmer quite a bit in the church where they recorded the Organ.
