Album  -- "Red"

This is the intro part:

Riff 1 |--------------------------|
       |--------------------------| 
       |--------------------------| 
       |--------------------------| 
       |------1-------1------1----| 
       |0--4----0--4----0--4---0--| 

Riff 2 |--------------------------|
       |--------------------------| 
       |--------------------------| 
       |---0--2----0--2----0-2----| 
       |1-------1-------1-------1-| 
       |--------------------------| 

Riff 3 |--------------------------|
       |--------------------------| 
       |--------------------------| 
       |---2--4---2-4---2-4-------| 
       |3-------3-----3-----------| 
       |--------------------------| 

Riff 4 |-12-9---14-12---15-14---7-9-|
       |----------------------------| 
       |----------------------------| 
       |----------------------------| 
       |----------------------------| 
       |----------------------------| 

The song goes like this:

Riff 1 (repeat)

Riff 2

Riff 1

Riff 2

Riff 3

Riff 4 lyrics begin
Riff 4 lyrics end

Riff 1

Riff 2

Riff 1

Riff 2
Riff 3

Riff 4 lyrics continue

After this there is a big gap in the middle and then it goes back to 
this sequence,
but slightly differently in timing.
