When I started playing guitar on my own (long time ago) I was influenced by Jimi Hendrix. I tried to play his riffs - and I failed most of the time - but eventually I got better at it, and quite soon I formed a band with my friends. Well, I wasn't the best musician in the world and nor were my friends, so we soon came into the conclusion that we (as a band) need professional guidance.
So we took lessons from this one awesome older guy who showed us all how to play.He often played some old recordings (tapes and vinyls) and showed us the notes and patterns and how to play those difficult parts etc.
One of the first songs he told us to practice and play was this:
This was especially difficult and frustrating for our drummer, because the intro is in 5/4 (four beats per time but you have to count to five - and therefore go one over every time). It wasn't easy for us other players either, but our drummer was totally losing his mind
