these are played over the main riff; you can figure out the timing
E|------------|------------|
B|------------|-7/\/\/\----| <-- bend the crap out of this note
G|-7---7------|------------| to get that strange high noise
D|-5---5------|------------|
A|------------|------------|
E|------------|------------|

those strange noises you hear in the background are samples. forget
about playing them.
the song ends with a low D chord over the main bass riff.
