I'm reliving this discussion to appreciate Jonas Mollberg' generousity to share his compositions in the internet. His compositions are outside the the box for traditional classical guitar pieces.
In addition to the famous Orion, he has many other pieces that are wonderfully composed based on classical guitar techniques.
I encourage all of you that are not familiar with his works to visit his website.
This is a quote on his book:
"One purpose of this material is to create a bridge between pop and rock music and the traditional guitar repertoire. As a guitar instructor, the author has often wished there was material based on classical guitar technique but at the same time sounding more like modern, popular music. He also felt a need for a body of literature which is idiomatic and really makes use of the possibilities of the guitar, so he created these pieces. The pieces frequently use open strings as one way of releasing the magic of the guitar. Another prominent element is the use of arpeggio technique, which provides a continuous and natural flow of music.
The book is aimed at guitar students as well as people who take delight in music that is melodious and easy to play but doesn't require too much technical skill to perform. The book is written in standard notation and tablature."
