I used to have a load of EVP recordings but I got rid of a lot of it in one of my periodical mp3 purges. I'll add the record you've mentioned above to my shopping list.
Did you ever hear this?
Yet another reason to love Tzadik.
The only problem I find is that in amoungst the strange ambient/ field/ found sound things there's a lot of total prickery. I really liked the idea of Aki Onda when I read about him, but what I've heard has severely irritated me.
I can't find any downloads of that dog pound found sound, which is a shame as it seems like the sort of agony I might well enjoy.
