For our last rock groove, let's mash-up two more giants of rock...Nirvana and Iron Maiden! The first part of this groove is an edgy aggressive line that can be played using a pick. Notice the dynamic markings in the chart, which add to the overall vibe when you play the first 8 bars quietly and then step on the gas when you repeat the section.
Starting at Bar 9, we have the sort of galloping groove that Steve Harris of Iron Maiden is famous for. This figure can be played with a pick as well, or you can really dig in with your fingers to get that signature sound. Be careful with the unison line at the end of the phrase, the whole notes sound best when played without any vibrato and as legato as possible.
