In this instructional DVD Denis Azabagic offers technical and interpretive tips on performing two of the most famous pieces in the classical guitar repertoire: La Catedral by Agustin Barrios Mangore and Introduction and Variations on a Theme by Mozart, Opus 9 by Fernando Sor. On a master-class level, Azabagic presents insightful technical advice, fingering suggestions and problem-solving exercises as well as a musical overview of each piece by movement or variation. While this DVD is specifically designed for those who wish to improve their performance of these two masterpieces, Azabagic's insights on musicianship and interpretation can be applied to virtually any composition.
