im not sure bout music 2 but im pretty sure music 1 can be up to 70% for prac performances
i played for some of the guys doing it this year and one of em got 20/20 for all his performances that i played with him for his trails.
majorin in guitar, blues and jazz oriented songs mainly, i havent decided on all my elective pieces but one of em will definately be "wonderful Slippery Thing" by Guthrie Govan because it incorporates so many styles and techniques, jazz, funk, blues, lead playing, rock etc.
