Here’s what Mitchell has to say about The Mouth Of Hell:
This piece was built around two tracks that were processed and edited to tape. One was made from recordings of my Panoramic Wave Generator instrument for Kontakt and played back on the Pioneer reel to reel. The second was made with a fascinating iPad app called Stria by Euginio Giordani and Alessandro Petrolati. The app recordings were edited and played back on the Akai cassette machine. Both tape machines were then bussed to the Lexicon processor.
The EMW 200 mini synth provides a droning, bass type sound. The remainder of the sounds are loops of processed vocals that are performed on an SP404 sampler, using the onboard effects and the Korg KPQuad.
