+<p dir="ltr">Tabbing this was very frustrating.&nbsp;Riff 3 is a
+masterpiece of guitar and vocal harmony, rhythm and guitar
+interplay.&nbsp; It has a bass intro and stacks guitars and vocals on
+top. This is the definition of Sleater-Kinney magic. You can't&nbsp;get
+it all done on two guitars.&nbsp; You can get close.&nbsp;&nbsp; I
+haven't done it justice.</p>
+<p dir="ltr">As usual the guitar 2's rhythms are vital to the S-K sound.&nbsp; It's still good if you don't get it just right.</p>
+<p dir="ltr">I sure hope I've done this well enough for you to figure out.</p>
