[Rwp] Perhaps a Bit OT: Silent Fan

[Chris Belle]

Those damn boom cars are the scourage of the earth, we have them around 
here too, these people have no consideration for anybody,
they think everyone for miles wants to hear their bass.
some cities are really tightening down on that sort of thing,
trucks and regular traffic noise doesn't even get in here at all, but 
that extreme bass is an invasion
of space, I think they even have trouble with some of that in big 
studios, those wavs are very long and  hard to stop, when some asshole 
has a thousand watts in his trunk,
you know we can track through a thunder storm,
here, but unless you have a whole floated room and lots of mass, you 
won't stop those super low frequencies.
