Backwards speaking is incredibly non-intuitive; to speak in true acoustic reverse, elements like dipthongs and plosive consonants have to be reversed, and they do so in surprising ways. To truly complicate matters, add in the backwards rise and fall of the intonations of speech.
There’s a particularly good mashup album available for download and I presume it’ll be “all the rage” among “the kids.” The group is called The Kleptones and the double album is called 24 Hours. The music includes artists from the 60s, 70s, 80s, 90s, Pop, Rock, Alt, Punk, Downtempo, Industrial, techno, rap, hip-hop, R&B, Motown, lots of sampling. No matter who you are, you’ll like at least one song. They’ve also got a decent music video on Youtube.[via]
