Duo Siedl/Cao is a composer-performer ensemble that ranges in the field between composition, improvisation, performance and live sound-installation. In their recent works they explore electro-acoustic sound as means of expression and reflect on performative aspects of a live concert situation.

Cao Thanh Lan and Gregor Siedl have dedicated themselves to an unusual instrumentation with their use of clarinet, modified zither, and live electronics. Their music is characterised by searching and experimental structures which generate tension and awakens the listeners curiosity through the relationship between compositional forms and improvisational interactivity. Works of Cao Thanh Lan and Gregor Siedl have been featured at international festivals and concert venues around the world, amongst others – Festival „Krieg singen“ im Haus der Kulturen der Welt Berlin, Opera Hanoi, FIME – Festival Intern, De Musica Experimental Sao Paulo, Festival Ankunft Neue Musik Berlin, Strom Festival Köln, FTARRI Tokyo, NOMART Osaka, Frischzelle Festival für Intermediale Performance, WIM Zürich, Porgy & Bess Wien, Sappho Taipei, CHELA Buenos Aires, Institut Francais, Monash University Melbourne, BoxHill Institute Melbourne, Universidad de Valparaiso. They have been touring in Europe, Japan, Brazil, China, Taiwan, Argentina, Uruguay, Chile, Finland, Vietnam, Australia and Indonesia.

Duo Siedl/Cao have been selected for the programme New Austrian Sound of Music 2018-2019 in the category Contemporary Music. Their music theatre “The fifth cardinal direction” has been selected to be presented at Operadagen Rotterdam 2018 and at Musiktheatertage Wien  2018.
