I came across this old late night session of sleepy Rhodes melodies and decided to render about fifty eight seconds of it. It was originally recorded on November 3, 2006 at about 12:53am. I love electronic timestamps.
There are two separate tracks of Rhodes, each running through separate processing. I added auto-panning to each track in opposite phase as a quick final touch before bouncing it down. The tracks are also running through equalization, amp modeling, two separate delays, and reverberation.

This spooky sound was created in Ableton Live using a variety of processing. The main device responsible is Pluggo’s Feedback Network. I ran a modulated synth pad into it, then removed all of the dry signal after automating several parameters. I re-sampled the results then pitched it all down two octaves being careful to filter out inaudible low frequencies. Finally, over the top I added a ping pong delay so the audio swirls around the stereo spectrum adding to the disturbing qualities of the sound. 
Absolutely nothing is distinguishable in these samples after all the processing that has been applied. My goal was to make a sequence of random samples sound as nasty as possible by applying down sampling, bit reduction, and distortion, then bring it back into something tolerable by applying some resonance filters and reverberation. 
I captured this Minneapolis skyway busking regular playing a mean version of Moonshadow by Cat Stevens on his accordion today during my lunch break.
