One of my favorite recommendations for contemporary works are these excellent etudes from Gerald Garcia. These etudes, as the composer suggests, are for the intermediate student from the third year of study onward (I would move that down to one or two years for some of the easier ones). However, some of the later etudes are pretty difficult.
Check out this praise from John Williams:
These studies are what students should be but usually are not: they use and develop specific areas of technique in a most musically imaginative and pleasurable way. The more traditional study collections usually take a single technical pattern for each study which then become like extended exercises. Garcia’s studies give the same benefit and also give you pieces of music. – John Williams, 1992
I love these because they have a variety of textures and moods ranging from aggressive raw sounds to beautiful choral textures. But I really like them because they are successful! That is, students are able to perform them and gain experience because the studies are so well suited to the modern classical guitar.
Garcia is an excellent guitarist himself and highly praised. He’s also well known as a teacher, arranger, and composer. You can study with him at various festivals if you are interested.
