This is another course, just like BSBB that I wish I had bought earlier. BSBB was about skills and getting my fingers to move more efficiently, but this, at least for me, is really about concentration. One of the problems about just learning solos is that you take in which lick goes over which chord, but then immediately forget and just learn the solo as a kind of whole. Now I have to really think. It took me quite a few days to get through the five minute backing track to the end without losing my way. The challenge I find, is if I do fluff a lick (not an unusual occurrence for me) or my mind goes off somewhere else is finding my way back into the track. Somehow that seems more of an achievement that just playing the whole thing perfectly.
