This recording is about contrast. Universes of timbres, harmonies, colors, rhythms and textures; acoustic music, electroacoustic, concrete, mixed; leading composers alongside burgeoning ones; Mexican and Argentine; traditional and alternative notations; complex hearing and simple listening; traditional techniques and extended ones; festive, dreamlike, sweet, terrifying, hopeful, pessimistic expression of sound... a violin and it's player. Such are the characteristics of the music in this recording and, in some ways, the sound representation of Abel Romero: excellent orchestral and chamber violinist, experienced child and youth pedagogue, with a profound knowledge of and gusto for both the traditional repertoire and the contemporary. Works by Lavista, Barcenas, Macias, Mary, Baca and Caballero concur, in all their multiplicity, on common ground with this great Mexican violinist. The works here presented, through their wise interpretation, all together form a diverse collection of music where unity is achieved, precisely, through the constant presence of contrast.
