produced various projects and productions, whether or not in collaboration with other parties. For Huid (Skin), a visual and musical performance from 2016 about tactile senses and making contact, SDH worked together with composer Arnoud Noordergraaf and the Utrecht theatre company Schweigman&. In 2015, the group performed in Tulpmania, a musical theatre production from De Veenfabriek and composer Yannis Kyriakides.

The Ives Ensemble plays modern chamber music in its purest form. Named after the idiosyncratic American composer Charles Ives, the ensemble is always on the lookout for surprising music. Composers such as John Cage, Aldo Clementi and Louis Andriessen have written music for the ensemble. They still work together with leading contemporary composers and artists such as Gerald Barry, Richard Rijnvos and Jan van de Putte. The ensemble performed the première of the three-hour musical theatre play De Optocht (The Procession), composed by Piet-Jan van Rossum. Other highlights include the Charles Ives Marathon (2014) in the Muziekgebouw aan ‘t IJ, a John Cage project in 2012, the Morton Feldman Vierdaagse in 2008 and the first integral Dutch performance of Cornelius Cardew’s seven-hour The Great Learning in 2006. The Ives Ensemble has released dozens of CDs over the past years with Composer's Voice and the Swiss label hatHut Records, ranging from works by John Cage and Morton Feldman to Clarence Barlow and Karlheinz Stockhausen. Rosa Arnold, Jeanita Vriens, Annemijn Bergkotte and Rebecca Wise together form the Ragazze Quartet. The quartet plays classical and modern string quartet music in innovative programmes, featuring collaborations with original voices in theatre and dance. In 2012, the quartet signed a contract with the label Channel Classics. Their first CD, Vivere (2013), received rave reviews in national and international press. Their third CD FourFourThree was released in May 2016 and received the 'Editor's Choice' Award in Gramophone. In October 2013, the Ragazze Quartet won the Kersjes Prize, awarded annually for exceptional talent in Dutch chamber music. They also frequently collaborate with young musicians and theatre producers, as well as leading organisations such as NDT and the Kronos Quartet, with whom they appeared at the 2016 Holland festival Soprano Claron McFadden comes from America, where she studied at the Eastman School of Music in Rochester, New York. She made her operatic debut at the Holland Festival in 1985 in a production of Hasse’s L’Eroe Cinese, which was first performed in 1990 at the Festival d’Aix-en-Provence in a sensational production of Rameau’s Les Indes galantes conducted by William Christie. She has since built up an impressive career. McFadden sings a wide repertoire, from baroque and contemporary music to jazz and cross-over projects. She's worked with leading conductors such as Kurt Masur, John Eliot Gardiner, Marc Minkowski, Neeme Järvi, Ton Koopman and Frans Brüggen, and with large orchestras and ensembles such as the Netherlands Philharmonic Orchestra, The King’s Consort, the BBC Symphony Orchestra, the Arditti Quartet and the Nash Ensemble. McFadden is a popular opera singer and has participated in productions of the Théâtre du Chatelet, the Glyndebourne Festival, the Salzburger Festspiele, the Bayerische Staatsoper and the Dutch National Opera. She performed in Claude Vivier's Rèves d’un Marco Polo, directed by Pierre Audi. During the Holland Festival in 2013, she performed in the 3D opera Sunken Garden by Michel van der Aa. Last year at the Holland Festival, she sang with Son Lux in the Concertgebouw. McFadden has made various recordings, including for EMI and has appeared in numerous radio and television productions. In 2006, she received the Amsterdam Award for the Arts. Christine Chapman studied at the University of Michigan and at Indiana University. She has been working as a professional horn player since the age of seventeen. In 1990 she settled in Germany. Since then, she has been working as a solo horn player with various European orchestras. She gained her first experience of an ensemble for new music in 2001, during a concert with Ensemble Musikfabrik. Since 2004, Chapman has been a permanent member of the Cologne-based ensemble. Two aspects about interpreting contemporary repertoire interest her in particular: the close collaboration with composers and the ongoing development of playing techniques and instruments. Together with instrument maker Gottfried Büchel, she developed a 'double horn', an instrument with two bells that can be played individually. As a member of Ensemble Musikfabrik, Chapman has worked together with various renowned composers, such as Karlheinz Stockhausen, Wolfgang Rihm, Peter Eötvös, Rebecca Saunders and Georg Friedrich Haas. She's also performed works by Harry Partch, Sun Ra, Mouse on Mars and La Monte Young. In both 2014 and 2016, Chapman performed with the Brass Academy, conducted by Marco Blaauw, during the Darmstadt International Summer Course for New Music. Christine Chapman is an ambassador of the Save the Horn campaign, launched by the Holland Festival.
