Between 2nd, 3rd verses (12/8 meter):
|--------------------------|  This is so atonal you could play just about
|--------------------------|  anything and it would sound close, which makes
|--------------------------|  it tough to figure out...

Then this riff, which repeats under Amott's lead:
|-----------------------------|  (The last time, instead of playing the last
|-----------------------------|   C#5 onwards, just play an E5(VII))
|-----------------------------|  (D5 slide to E5 is just a grace note)
