A very interesting example of hocketing/fission/streaming that also
makes use of the phenomena of difference tones is to be found in
several of Maryanne Amacher's compositions on here CD on Tzadik:

Sound Characters (Making of the 3rd Ear)
Tzadik #7043 Released Feb. 1999

She tunes hocketing tones such that they combine to create one or more
"extra" difference tones. Quite interesting to hear. You have to turn
it up quite loud to get the effect.
