||"Contemporary Etudes for the Acoustic Guitar" by Chris Olson was written in 2005. This is a wonderful collection of twelve etudes written by a master teacher who is really interested in helping the late beginner to intermediate guitarist. The etudes are all written with standard tuning in mind and retuning is not necessary to play these cleverly conceived works. New sounds abound here and a CD with 24 cuts is included. Highly recommended!
