Welcome back, 13jcouto!!

Love that you are feeling that sparkle!

I'd suggest you go with Rock 1 - you may want to backtrack a bit, or, all the way to the beginning.

And if, in that process, you discover you are rusty on some Fundamentals, then go ahead and find some lessons in one of the Fundamentals Courses that will help clarify and hone whatever you are rusty on, or unsure of.

I say this because I'm assuming you were drawn to Rock 1 because that is the kind of music you would love to learn to play. If that is true, then that is where the "Sparkle" lives. 

Pursue the music you love - and fill in the skill-or-understanding blanks as needed. 

Have fun! -Lisa
