The first concert of the season by the Orquesta de Cámara del Auditorio de Zaragoza "Grupo Enigma", this 6 November in the Sala Luis Galve of the Auditorio de Zaragoza, features the Spanish premiere of Diferencias by the Zaragoza-born composer Jesús Torres. Commissioned by the conductor Ernest Martínez Izquierdo for Ensemble Barcelona 216, with the intention of premiering it at the 1999 Strasburg Festival, the piece was finally premiered in London, under the direction of André de Ridder with the Royal Academy Ensemble. The title "Diferencias" refers to 16th-century Spanish music; without formal references, it is rather a homage to a period and style the composer admires, similar to what he does in the works "Glossa" or "Tiento". Jesús Torres' presence this autumn in the music programme of his native city is worthy of note: this past 28 October, the Trío Arbós presented in Zaragoza the piece "Trío", dedicated to this wonderful ensemble. This 12 and 13 December see performances at the city conservatory's Auditorio Eduardo del Pueyo of his "Cuentos de Andersen", for narrator and chamber ensemble, premiered in Madrid last year. Among his recently published works, we should mention "Presencias" for solo piano and "Chacona" for solo violin, both new additions to the Tritó Ediciones catalogue.
