Breath and Sounds tape

[Sean Kennedy]

So I found the Beatrice Witkin piece "Breath and Sounds for tuba and tape." But sadly I only found the score and no tape. And from my own research it is nowhere to be found in the ILL system. Does anyone have the tape or maybe a copy of it?

I also found the lp of Toby Hanks recording, so I know that it must be out there somewhere....
