-6  -5  -6 (slowly slide between this holes/chord)
 -6  -5  -6'  -6 (intonation and time is important)
            
That's it. Try to find your own mixture of chord play and
intonation. The bend -6' makes the ugly cool sound.
I used an echo-effect for this song, edited by software, but
you can also play in a garage and record it.
