I was wanting to do the same.... I just recently been going to sit down lessons (about a month now) and he has me learning searies 1, 2, and 3 barr chords. Once I started getting those down a bit I found I was playing some cool rock songs I couldent before learning the barr chords. I recomend trying to get a good feel of them and the songs will come easy. I know I tried to play "Brain Stew" by Green day months ago and was horrible at it (I know to most it is an easy song).... I got the barr chords down enough now I can rip the crap out of that song.... Ahhhh the power of rock.... :)
