Duo Signal

We are a chamber music group formed by saxophone (Alejandro Oliván) and trombone (Adrián Albaladejo) with a determined commitment to the performance, creation and diffusion of new repertoire.

Since our inception, we have developed many initiatives to encourage the international creation of new music, commissioning and world-premièring pieces by: Kevin Juillerat (CH, 1987), Lanqing Ding (CN, 1990), Fernando Manassero (ARG, 1984) Mioko Yokohama (JAP, 1989), Dativo Tobarra (ES, 1993), Santiago Díez- Fischer (ARG, 1976), Nuño Fernández Ezquerra (ES, 1992), Jon Yu (USA-TWN, 1988), Jaehyuck Choi (KOR, 1994), Emre Eröz (TUR, 1995), Nicolas Rouvile (BEL, 1989). Future commissions include pieces by Luis Codera Puzo (ES, 1981) and Claudia Jane Scroccaro (IT, 1984).

Aware of the necessity of helping performers and music creators to thrive in their professional career, Duo Signal has always coupled their commitment to the performance of new music with diverse pedagogical initiatives.

Duo Signal always proposes music for the inquisitive ear. Each concert has a different meaning and we adapt our repertoire with the aim of exploiting the sonic possibilities of the space and the context. We have featured from purely instrumental pieces to the expansion of the group with the addition of audiovisual elements, enthralling the audience with the myriad of possibilities residing in this duo of instruments.
