Thanks to all who gave their voices.
I sampled some randomly off my laptop into the Koala app on my iPhone. Later, while waiting for children who were at a rehearsal for a musical, I worked on this. Ambient, I did some reversing and pitch shifting, all in Koala. Then into AUM and added a little tape delay with K7D.
Alone is a dark parking lot in a car, using the bluetooth connection to use the car stereo as speakers. People were all around me then, or at least their voices.
Thanks again, and thanks MW.
