The chord progression goes like this.
B C# G# B
B C# E D#m C#
You can play them as power chords, I'm pretty sure the original goes that way, but the
sound is a lot fuller if you're playing it like this on your own.
The chord progression changes after a while, and the only part that differs is the very
end of the progression.
Like this.
B C# G# B
B C# E F# C#
