I'm listening to Recitations yet again, I'm starting to love it.
There is something about it that is giving me ideas of a way to apply a concept that I've have for quite a while, into vocal music.
These pieces (Recitations) are quite overwhelming and I know what Snyprrr means in the original post about it.
Return to this thread Snyprrr, I need your mentoring in all things Aperghian! 
Check out some of the YouTube versions of
Recitations -- there are many, and these little gems are much better when you can SEE the performers. Many of them involve ordinary sounds such as coughing, clearing the throat, etc., which can sound like accidents (but of course, they're not).
One of them has the singer dropping music on the floor. When I saw it performed, it was for just a small group of people in the singer's home. I was sitting on the front row, and when she dropped the score I reached down to retrieve it. She grinned at me and shook her head -- and then the dropped music became a repeated thing, like a little fugue. Great fun, hilarious, educational.
Just watched this video of Nos. 8 and 11 for the first time by a singer new to me,
Sarah Maria Sun -- wow!
