Sorry, but I just don't get it. But then, some people think all old time fiddle tunes sound the same (some banjo tunes actually do).
What you might find interesting in those Library of Congress collections are little vocal snippets and the street and industrial sounds that could work as percussion instruments. That's what I was playing around with, using a drum machine as a timekeeper and then gradually getting rid of its sounds as I fit noises into the pattern. Nothing I though worth sharing, though someone who gets the genre better than I do would probably do a much more musical job.
Well, I had no idea what I was going to do in the first place and my only intention was to annoy because I found it amusing. The provided cat sounds were all "cute" and "nice kitty" sounds so I knew I had to strike terror into the hearts of all felines. I love cats but they are jokers so the joke was on them for once.
In other words, I don't get it either. Now Ray Stevens recording Guitarzan - that I get. The Streak was pretty funny. I won't mention others, don't want to ruffle feathers or offend somebody's delicate sensibilities.
I'm of the opinion that all humans are absurd and should be ridiculed. I do not exclude myself. It's not very PC of me, so it goes. They had some good sound effects on the Benny Hill Show too.
And, I do own a banjer, it was a Bell kit for a Boucher fretless banjer that went way too cheap on eBay. Fortunately for the world, I can't do much with it - yet.
