In former days the composers/sound engeneers had to do bizarre, dangerous and funny things to get special takes of sounds underwater, windy etc. With the approach of modern computer-technology to every household we can get the same results without leaving our armchairs or at least our studios. The keyword is convolution, a mathematical method for combinig the impulse response of one space or thing with a different sound. So if You convolve e.g. the impulse response of a gas-tank with Your favorite song, sung maybe by Your children. You can hear how it would sound like without moving anybody anywhere.

So what did I do?

I took a text of Hank Bull and convolved it with different homemade
impulses. Unfortunately I did not have the original voice of H.B. at
hand, so I used a computer voice to read the text. You hear the following parts, the impulse response files and the convolved texts.:

1.)For comparison my original voice, speaking underwater in the
kitchen-sink, greeting the listeners.

2.)IR (Impulse response): kitchen-sink filled with water.

3.)I am not arguing here for a happy global community of computer
pen-pals, although that's part of it.

4.)IR: letting the water out of the kitchen sink.

5.)National mass-media networks are designed to centralize and control information flow, when communications systems should be used on a much more local and esoteric level.„

6.)IR Bowl filled with water

7.)Politically, a problem develops whenever administration is separate
from the everyday job of operating businesses; whenever management is separate from labour.

8.)IR espresso cup filled with lukewarm coffee (not to kill the mike)

9.)Structurally, the battlefield is divided into two interlocking areas
- the centralized and the de-centralized.

10.)IR psion palmtop 3mx

11.)The strategy is to aim for a very loose structure.

12.)IR Toy sampler

13.)The ideal is to have no structure at all and to move freely between
structures.

14.)IR me sipping the coffee

15.)Be on different networks - the radio network, the mail network, the
Eternal Network.

16.)IR splashing in the bowl

17.)Be on your local scene.

18.)IR Ukelele

19.)Be internationally famous.

20.)IR turntable

21.)Use the museums.

22.)IR banjo

23.)Start your own gallery.

24.)IR relay

25.)Sell to collectors. Give your work away for free.„

26.)IR lapsteel

27.)Avoid bureaucracy.„

28.)IR my voice box

29.)Visit each other.

30.)IR E-guitar

31.)Use computer mail systems.

32.)IR screw falling in kitchen-sink

33.)Contribute to magazines. Subscribe.

34.)Learn to operate machines. It's easy. convolved with

35.)IR E-guitar long.

(The order has no deeper meaning)

( For the all to serious: I know that, strictly taken, convolution works
only with linear systems)
