I'm in a bit of a rut and would like to buy some sort of course that would help my playing. I'm thinking of licks, improvisation and melodic soloing like Santana and Slash etc. I'm not looking for Skype lessons or anything like that as I live in the Falklands and the internet is awful. I want a course I can buy, download and work through at my own pace. Does anybody have any suggestions of where I can go to get such things that are excellent quality?
