Duo Signal

Stablished in 2019 in Basel (Switzerland), Duo Signal is a chamber music group formed by the trombonist Adrián Albaladejo and the saxophonist Alejandro Oliván, with a clear commitment to the creation and diffusion of new repertoire. Both members of this duo have an extensive professional career, have performed in some of the most important contemporary music festivals of the moment. In the year 2023, Duo Signal was awarded with the second prize in the prestigious Swiss contemporary music competition “Concours Nicati 2023”. 


Since its inception, Duo Signal has developed several initiatives to encourage the international creation of new music. In addition to selecting specific composers, Duo Signal organises a “Call for Scores” every year which allowed them to commission to 6 composers to date, apart from discovering the music of very talented artists. 


Duo Signal has commissioned and world-premiered pieces by composers such as: Santiago Díez- Fischer (ARG, 1976), Nuño Fernández Ezquerra (ESP, 1992), Jon Yu (USA-TWN, 1988), Jaehyuck Choi (KOR, 1994), Kevin Juillerat (CH, 1987), Emre Eröz (TUR, 1995), Dativo Tobarra (ES, 1993), Nicolas Rouvile (BEL, 1989), Fernando Manassero (ARG, 1984) or Mioko Yokoyama (JAP, 1989), Luis Codera (ESP, 1981), Hunjoo Yung (KOR, 1981). Future commissions include pieces by and Claudia Jane Scroccaro (IT, 1984). 


Since 2020 Duo Signal has annually organised its own concert seasons in the main cities of Switzerland and has participated in festivals such as Potries Music Fest (ES) or Klexos LAB (ES). Every two years they celebrate Signal +  a project where the duo expands the instrumentation with the addition of different outstanding musicians of contemporary music scene. For instance, we have collaborated with Alexander Gabryś, Kirill Zvegintsov, Jürg Henneberger and Marcus Weiss' saxophone class. Future collaborations include the soprano Sarah Maria Sun or the guitarist Francesco Palmieri, amongst others.


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. One example is our project Signals, a series of interviews to get to know better the composers with whom we collaborate.


Apart from being active teachers of their respective instruments (in the form of individual masterclasses or teaching at conservatoires) they have curated diverse pedagogical projects. As an example of the latter stands out the collaboration with the Conservatoire Supérieur of Castile and La Mancha, where they guided composers in all the stages of the creation of a piece: from giving masterclasses on advance writing for saxophone and trombone to the final performance of the composer’s pieces in concert. 


Duo Signal always proposes music for the inquisitive ear. Each concert has a different meaning and they adapt their repertoire with the aim of exploiting the sonic possibilities of the space and the context. They 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.
