All Caps

The riff (goes in a continous loop):

e|----------------------------------------|
B|----------------------------------------|
G|--8-------------------------------------|
D|----9-----------------------------------|
A|------11-9-11---------------------------|
E|---------------12-11-9------------------|

That's pretty much it. Very cool piano riff, sounds very low and bassy so you can also try downtuning to like
drop C# or something for it to sound closer and move the rest of the riff down one octave, like this:

 e|----------------------------------------|
 B|----------------------------------------|
 G|----------------------------------------|
 D|--1-------------------------------------|
 A|----2-----------------------------------|
C#|------7-5-7-3-2-0-----------------------|
