If you've decided that neo-classical guitar will be the mainstay of your playing style,I suggest you study Yngwie Malmsteen,especially his early stuff."Far Beyond the Sun" is the gospel of neo-classical guitar playing.Yngwie himself cites Bach,Vivaldi,and Mozart amongst his chief influences,studying their music may also help.Fortunately or unfortunately,choosing the path of neo-classical requires incredible discipline and dedication,to be done right.
