Jeremy Messersmith - Knots chords

Chord wise, this song is really easy. The tricky part is all the riffs.  For the verses 
and chorus just pick the chords.  If anyone can figure out the riffs that would be awesome.

G       C
Black sweatband, sticks blur in her hands; she's the drummer
G                                                  C
She weaves a beat through Kinks and Deep Purple covers

Am              D
Can't shake her off
          Bm       Em
She keeps me tied in knots
      Am                              D
I'm tangled from the inside out
