@terminalcity Well, I can assure you that the original sound source is a field recording in the most literal sense, of a combine harvester in the field. You can hear my dog barking and also birds tweeting. The techno sound comes from the fact that I used a filter gate on the sound when I was messing around with Reasons Alligator. :)
This is the second sound on freesound that I like more than many other fully-fledged songs out there. (The other one being the one by schlupipuppie, where he vocoded something by the construction sounds). Except that this is more trippy!
