For the Guitarist out there!

This instructional video of John Petrucci (Dream Theater) called "Rock Discipline". It really works for my growing guitar skills. In my opinion, this video really works for progression of those intermediate players out there. You should try this one if you still have not watched this and if you want to improve your playing.  Happy watching! and good luck to learning. :)

Watch all the series of this video from part 1 upto the final part.
