A few years ago, I made some friends on the Internet when I recorded a scratchy version of Paul and Linda McCartney’s “Ram” on 45 RPM into my computer and put it on SoundCloud. You can read the story behind that here, although I recently disabled the audio.
One of those friends, Alan Benard, liked what I did but thought it sounded a little Chipmunky and altogether too scratchy. So, he recreated the effect digitally and then pitched it down (using math, I presume) to, in his words, “squeeze all the marijuana out of it.”
I’m not sure why he’d want to squeeze the marijuana out of the record, and anyway that’s impossible because marijuana’s fat soluble. Everybody knows that. But while his motive may have been dubious, he did succeed in making something thoroughly enjoyable.
