Tom DePlonty and I recently made an album called The Detail of Little Events . In it we used recordings of voice in the public domain from the web, and I found the use of natural voice to create instruments in my software synthesis units (Iris, stuff like that), that I made an album, Sol. La. Fa. , which uses voice as the basis for the entire set. There are twelve shorter pieces on the CD, and some are taken from the Sacred Harp tradition ( Windham ), some from just folk tunes ( Old Granny Hare ), from hymnals ( Ancient of Days ), and some just from my voice ( Het uitzicht vanaf de berg ). I was going to call the album Fasola, but isn't that already taken?
