Many electric guitarists, whatever style they are playing, are interested in Classical music. Quoting for example Larry Corryel (fusion Jazz), Elek Bacsik (Jazz), Yngwie Malmsteen (Hard-Rock), etc.
It is true that the Classical repertory is very instructive and lends itself to various interpretations, adaptations and (or) variations, especially in Jazz and Rock'n Roll.
This guitar course is suited for all kind of guitarists who desire to learn this style of music, be it for its intrinsic beauty, phrasing practice, or increasing one's technique.
