Brian's Elevator Music Tapes

Brian's Elevator Music Tapes are a series of vinyl records, compiling together various pieces of music, presumably used in elevators. Although no elevators in our universe have ever played such music, or indeed anything similar. They are forbidden in most places on the material plane, however some copies have been known to randomly appear at the bottoms of children's' swimming pools from time to time.

Appearance
The records appear in card envelopes, marked with the name "Brian's Elevator Music Tapes", followed by the word "Volume" and a number, which is believed to denote its position in relation to the other Tapes before and after it. The card envelope also has an impressionist painting of a lone elevator, with the doors only slightly ajar. From within the gap between the sliding doors can be seen a soft, yellow light, behind the form of a Faceless Man wearing a bowler hat and black robes.

History
It is unknown where the Tapes come from, or who made them, despite clearly being labelled "Brian's" on the cases they come in. No one has been able to uncover any information about this Brian, and nobody has come forth claiming to be him. To this day the creation and identity of the creator remains a mystery.

The first recorded instance of the Tapes being found was when, what is now known as Volume One, appeared in the swimming pool of Mrs. Pereditory's Home For Criminally Insane Children, discovered by none other than Annie the Assassin, nowadays well known for her later exploits with the Gang of Five, alongside Michael Mouse. Not knowing what a vinyl record was, she began to chew it, before her unusually needle-sharp teeth scratched over exactly the right spot on the record, causing the compiled pieces of music to flow from her ears. This was noticed by Mrs. Pereditory and she confiscated the record. She took it to her private office and listened to it once through, before immediately calling the authorities and begging them to take the record from her possession before it "consumed her whole".

Volumes
So far only three volumes have been released, several copies of each being found throughout children's pools everywhere. Volumes Three and Four have not yet been uncovered.
 * Volume One
 * Volume Two
 * Volume Five
