As part of my research regarding early American percussion ensemble music, I began corresponding with [Gordon Mumma](https://en.wikipedia.org/wiki/Gordon_Mumma) about recordings that he acquired from John Cage in the 1970s. Found below is information that Gordon provided about the recordings as well as the digitized recordings that were created at and acquired from the [Stanford Archive of Recorded Sound](https://library.stanford.edu/ars). The collection can be viewed in the Stanford Library catalogue here: [John Cage Disc Collection](https://searchworks.stanford.edu/view/nh778zd7225). The following is a two page document that Gordon wrote to share the story about how he acquired about these early recordings: ![[Mumma - CageEarlyRec.nt 00-08-12.pdf]] ![[cover.jpg]]
