in many of his pieces, including Dark Dream for Orchestra (2013) and Concerto grosso no.1 for four alphorns and orchestra (2014). Concerning the overwhelmingly sombre nature of his oeuvre, Haas says: ‘I composed an extensive repertoire of darkness during several decades.' The titles of such operas as Nacht (1995; 1998), Die schöne Wunde (The Beautiful Wound, 2003), Melancholia (2006-07) and Bluthaus (Blood-House, 2010-11) speak volumes, although in his orchestral work Hyperion (2000) he made use of composed lighting effects, and in his piano trio Ins Licht (2007) he explored what he describes as a more cheerful median of sound for the first time. The German-Austrian music tradition also forms a recurring theme in Haas’ work, as can be heard in his Torso (2001), an orchestration of Schubert's unfinished piano sonata in C major (D. 840), and Sieben Klangräume (2005), a companion piece to theMozart Requiem. Haas is the recipient of the Großer Österreichischer Staatspreis, the 2012 Music Award of the City of Vienna 2012, and the 2013 Musikpreis Salzburg, among others. A former member of the faculty of the Hochschule für Musik Basel, he has taught at Columbia University, New York, since 2013. Mollena Lee Williams-Haas is a writer, actress and storyteller.

Dutch conductor Bas Wiegers (1974) began his career as a violinist, but now primarily devotes his time to conducting, focusing on contemporary repertoire. He studied violin and orchestral conducting at the conservatories in Amsterdam and Freiburg. In addition to collaborating with Klangforum Wien, Ensemble Musikfabrik, Ensemble Modern and ASKO|Schönberg, Wiegers has regularly worked with the Rotterdam Philharmonic Orchestra, Residentie Orkest/The Hague Philharmonic, the WDR Symphony Orchestra and the Estonian National Symphony Orchestra. Wiegers often appears at various international festivals, and he conducts the works of such living composers as Harrison Birtwistle, Louis Andriessen, George Benjamin, Oliver Knussen, Georg Friedrich Haas and Helmut Lachenmann. In 2009, Wiegers received a conducting grant from the Kersjes Foundation, and a ‘Momentum’ grant from the Performing Arts Fund NL to explore the contemporary concert experience. During the 2017-18 season, Wiegers will again lead numerous projects with Klangforum Wien in Austria, Italy, Mexico, the Czech Republic and Germany. He will make his debut at the Kölner Oper with an opera by Helmut Oehring, and will also debut with the Neue Vocalsolisten Stuttgart.

Gunde Jäch-Micko was born in Vienna, where she grew up with her six siblings. Her interest in music developed very early on; she studied the violin, folk-harp and piano, focussing on folk music in particular. From 1978 to 1991 she trained at the University of Music in Vienna with Michael Frischenschlager, Ernst Kovacic and Gerhard Schulz. In particular she is interested in chamber music, playing in various small ensembles up to chamber orchestra size. For several years she studied the baroque violin as well as baroque playing techniques. She was awarded several prizes at the Austrian “National Competition Jugend musiziert” as well as at various international violin competitions. Gunde Jäch-Micko has performed as a soloist as well as with chamber music ensembles both within Austria and internationally and has recorded variously for the radio and on CD throughout the last 25 years. She became a member of Klangforum Wien in 1990. Krassimir Sterev was born in Bulgaria where he started his musical education in Plovdiv. He continued his studies at the University of Music, Graz, as well as in Denmark where he held a scholarship from the Royal Danish Academy of Music, graduating as accordion soloist. His musical development was strongly influenced by teachers like Mogens Ellegaard, James Crabb and Georg Schulz. Krassimir Sterev performs internationally as a soloist and member of chamber music formations, ensembles and orchestras and plays at many renowned festivals. His engagements include appearances in various theatre and dance theatre productions and projects specifically developed for children. Krassimir Sterev became a member of Klangforum Wien in 2003.

In addition, Krassimir Sterev focusses his attention on the development of a special repertoire for accordion. Many composers have written new pieces for him – amongst them Bernhard Lang, Pierluigi Billone, Bernhard Gander, Olga Neuwirth and Aureliano Cattaneo – which he premièred. Lukas Schiske was born in Vienna in 1962. He trained both as a classical and as a jazz percussionist at the University of Music and Performing Arts in Vienna. Following his studies, Lukas Schiske worked with classical symphony orchestras such as the Los Angeles Philharmonic, the RSO Sinfonieorchester and the Wiener Symphoniker as well as with several baroque orchestras. In addition, he has performed with various chamber music ensembles covering a wide range of musical styles, and collaborated with artistic personalities such as Michael Heltau and Claude Bolling. Over the years he has increasingly specialised in new music. Both as soloist and as ensemble player, Lukas Schiske is a regular guest at the most renowned international music festivals including Wien Modern, Wiener Festwochen, Bregenzer Festspiele, Lucerne Festival, Darmstädter Ferienkurse, Donaueschinger Musiktage, Biennale Venedig, Huddersfield Contemporary, Sacrum Profanum Cracow and Ultima Oslo. Over the years he has forged close artistic relationships with composers such as Georg Friedrich Haas, Beat Furrer, Salvatore Sciarrino, Georges Aperghis, Olga Neuwirth, Rebecca Saunders, Mauricio Kagel and Luciano Berio. Since 2013 he holds a teaching position as professor for new playing techniques at the University of Music and Performing Arts (mdw), Vienna. Lukas Schiske has been a permanent member of Klangforum Wien since its inception in 1985. In Klangforum Wien 24 musicians from ten different countries represent an artistic idea and a personal approach that aims to restore to their art something that seems to have been lost, gradually, almost inadvertently, during the course of the 20th century: music which has a place in the present, in the community for which it was written and that wants to hear it. Ever since its first concert, which the ensemble played under its former name, the Societé de l’Art Acoustique, at the Palais Liechtenstein under the baton of its founder Beat Furrer, Klangforum Wien has made musical history. The ensemble has premiered roughly 500 new pieces by composers from three continents. Klangforum Wien can look back on a discography of over 70 CDs, a series of honours and prizes and around 2,000 appearances at renowned festivals and in the premiere concert and opera venues in Europe, the Americas and Japan, as well as various youthful and original initiatives. The members of Klangforum Wien come from Australia, Bulgaria, Germany, Finland, France, Greece, Italy, Austria, Sweden and Switzerland. Sylvain Cambreling, Friedrich Cerha and Beat Furrer are three outstanding musicians who have been awarded an honorary membership of Klangforum Wien through an unanimous decision by the ensemble. Sylvain Cambreling has been principal guest conductor since 1997.
