As seen in:

So I know the main chord progressions is E-A-E-B-A-B.
They do this one riff 34 seconds into the 2nd link where its something like

E: ----------------
B: --------------0-
G: ------2---------
D: ----2-----1-4---
A: 0-4-----2-------
E: ----------------

Cept what their guitarist plays sounds higher?
And 52 seconds into the 2nd link they play the first half of that riff cept it sounds like it's chords.

Can anyone help me out here?
Be excellent
