That's one crazy beat, like wow man, GROOVY! I have no idea what that possibly could be, never heard anything like it but I sure had fun mixing it up with a digital editing suite. At one point it sounded like those tom toms you hear in cartoons when the character takes of running. Next time I get blasted I'm gonna loop it and crank the volume! (;->)
Yep, I played it backwards, too. That's what it sounds like. I highly doubt it was received off the air. Funny thing, though... I hear noises kinda like that that changes in time to the typing on my keyboard, if I use an inside antenna.
