The first series of duets were written because teaching material for chamber music courses Cabrera has been coordinating was needed. These ten pieces were all composed from March to July 2006 with the specific purpose of making use of a few technical aids typically associated with this combination of instruments. Sergio Fernández Cabrera: A composer, guitarist, arranger and conductor born in Montevideo Uruguay, Sergio Fernández Cabrera has created music for chamber and symphonic orchestras, choirs, theatre and dance. His outlook as composer and guitarist with regard to both folk and contemporary composed music have ensured he has always remained creative and continually in search of new challenges. He has incorporated the most important features of music of the RÃo de la Plata, such as milonga, tango and candombe, into the body of his work, in a manner which arrives at a perfect synthesis of various music genres which originally are quite different in nature, without excluding original and daring ideas. Umbral: The Umbral guitar duo, consists of Ignacio Correa and Sebastián Segarra and was formed in 2006 when together with Sergio Fernández Cabrera they worked on a few performances of chamber music. These two Uruguayan guitarist want to spread Latin American music to the world and they have found their niche as musicians with a repertoire that requires both academic discipline and a serious approach to style of folk art
