The song Experiment Iv is performed by Kate Bush in the album named The Whole Story in the year 1990 .
We were working secretly
For the military
Our experiment in sound
Was nearly ready to begin
We only know in theory what we are doing
Music made for pleasure
Music made to thrill
It was music we were making here until
They told us, all they wanted
Was a sound that could kill someone
From a distance, so we go ahead
And the meters are over in the red
It's a mistake in the making
From the painful cries of mothers
To the terrifying scream
We recorded it and put it into our machine
Then they told us, all they wanted
Was a sound that could kill someone
From a distance, so we go ahead
And the meters are over in the red
It's a mistake in the making
It could feel like falling in love
It could feel so bad
But it could feel so good
It could sing you to sleep
I'll bet my mum's gonna give me
A little toy instrument
But that dream is your enemy
We won't be there to be blamed
We won't be there to snitch
I just pray that someone there
Can hit the switch
But they told us, all they wanted
Was a sound that could kill someone
From a distance, so we go ahead
And the meters are over in the red
It's a mistake we've made
And the public are warned to stay off
