Charlotte Margiono
It all started at the Conservatory of Arnhem, where Charlotte was more or less ‘discovered’ by Aafje Heynis, with whom she completed her studies as a Performing Artist in 1982. Later, after two years at the Opera Studio in Amsterdam, Charlotte left for Berlin where she continued to learn under the passionate guidance of director Harry Kupfer.
Back in the Netherlands, Charlotte met her manager and good friend Pieter Alferink, who, from that moment on, took care of all of her artistic engagements – and still does to this day. The first engagement she obtained through him was a series of concerts, in 1986, in Rotterdam with James Conlon, where she sang as a soloist in Mahler’s Symphony #2, together with contralto Jard van Nes.
A variety of different roles in various international opera houses quickly followed. The highlights of Charlotte’s career include: Berlin, where she sang Mimì in La Bohème under Rolf Ruiter and Harry Kupfer in 1984; Amsterdam, where she performed Fiordiligi in Così Fan Tutte under the baton Nikolaus Harnoncourt, directed by Jürgen Flimm; London, where she recorded Beethoven’s concert aria “Ah, perfido!” with Sir John Eliot Gardiner in 1991, and Salzburg that same year: Vitellia in La Clemenza di Tito with Sir Colin Davies and director Peter Brenner. In 1993, she sang the soprano solo in Haydn’s Die Schöpfung with Frans Brüggen. In 1994, she performed Desdemona in Verdi’s Otello with Antonio Pappano, Donna Elvira (Don Giovanni) in Parma, conducted by Sir John Eliot Gardiner and directed by Lorenzo Mariani, and the Contessa in Mozart’s Le Nozze di Figaro in Tokyo with Claudio Abbado and Jonathan Miller. In London, 1995, she performed Strauss’ Vier Letzte Lieder with Bernard Haitink. A little later came a stretch of especially fond memories in her home country: the title role in Dvorak’s Rusalka with Leos Svarovsky in Utrecht and a lied recital in Rotterdam with conductor Ed Spanjaard (1998), Marguerite in Berlioz’ La Damnation de Faust with Bernard Haitink (1999). In 2001 she sang in Beethoven’s Fidelio as Leonore with Simon Rattle, conducted by Deborah Warner. After that came Elsa in Wagner’s Lohengrin with Edo de Waart and Pierre Audi (2002), Szymanowsky’s Stabat Mater with Jaap van Zweden and Wagner’s Die Walküre as Sieglinde with Hartmut Hänchen and Pierre Audi (2004), all in Amsterdam. Then in 2005 came Der Freischütz in New York City, where she sang Agatha under Eve Queler. In 2011 Simone Young and Charlotte Margiono performed a selection of Alma Mahler songs in Hamburg, Germany.
Another immensely important part of her career is her musical partner and the other half of her Lied duo: Peter Nilsson, with whom she has done many beautiful and exciting recitals.
The CD recording and concerts in collaboration with pianist and composer Frans Ehlhart – singing his own compositions with texts by Ingrid Jonker – is also a highlight in her musical life.
Charlotte Margiono has been teaching for quite a while. From May 2008 until June 2015, she was a main subject teacher at the classical voice department of the HKU Utrecht Conservatory. For the past ten years, teaching has been a very important part of her life. She teaches privately in her studio, and guides a number of young singers, all working at different levels as singers and performing artists. For her, this work is equally fulfilling as singing herself, only in a completely different way. The stage now plays a small but joyous part in her life, as a role here and there, a recital, or a concert with an orchestra – but passing on the craft and artistry of music and singing is now her main passion.

Dietrich Henschel
Baritone Dietrich Henschel captivates audiences as a regular guest at major opera houses, an esteemed interpreter of lieder and oratorios as well as with his multimedia projects. His repertoire stretches from Monteverdi to the avant-garde. Born in Berlin and having grown up in Nuremberg, he made his debut in 1990 at the Munich Biennale for New Music and first became known internationally from 1997, following a period as an ensemble member of the Opera Kiel. At the Deutsche Oper Berlin he took the title role in Hans Werner Henze’s Prinz von Homburg, staged by Götz Friedrich, and gave an outstanding lead performance in Busoni’s Doktor Faust at the Opéra de Lyon and the Théâtre du Châtelet in Paris, for which he won a Grammy.
The singer’s major roles include Rossini’s Figaro, Wolfram in Wagner’s Tannhäuser, Monteverdi’s Ulisse and Orfeo, Mozart’s Don Giovanni, Beckmesser in Wagner’s Die Meistersinger von Nürnberg, Alban Berg’s Wozzeck and Dr. Schön in Lulu, Golaud in Debussy’s Pelléas et Mélisande and Nick Shadow in Stravinsky’s The Rake’s Progress, with which he makes regular appearances at the major European opera houses. Contemporary composers such as Péter Eötvös, Detlev Glanert, Manfred Trojahn, Unsuk Chin, Peter Ruzicka and José-Maria Sanchez-Verdu have all dedicated leading roles in their operas to the baritone.
In addition to his operatic work, Dietrich Henschel is committed to the performance of lieder and concert works for voice. In orchestral concerts he has worked with conductors such as Riccardo Chailly, Kent Nagano, Cornelius Meister, Sylvain Cambreling and Semyon Bychkov. His collaborations with John Eliot Gardiner, Philippe Herreweghe, Nikolaus Harnoncourt and Colin Davis are documented on numerous oratorio recordings. Dietrich Henschel is particularly interested in theatrical and multimedia presentations of vocal music. He has performed staged versions of Schubert lieder cycles at La Monnaie, Theater an der Wien, Den Norske Opera Oslo and the Komische Oper Berlin, among others. In the project IRRSAL – Triptychon einer verbotenen Liebe, featuring the orchestral songs of Hugo Wolf, he combined film and live concert; his project featuring songs by Gustav Mahler, WUNDERHORN, was a collaboration with director Clara Pons, and was developed as a co-production between several European partners including De Doelen, La Monnaie and the BBC Symphony Orchestra London.
Last season, Dietrich Henschel presented a varied repertoire: in addition to taking on the lead male role in Chaya Czernowin’s world premiere Heart Chamber at the Deutsche Oper Berlin, he toured Japan with the Sapporo Symphony in promotion of his new recording of Schubert’s Die schöne Müllerin, he performed at the Schubert Festival with the Orchester Symphonique Montréal in Canada, and he also premiered his new Christmas project X-mas Contemporary, created in collaboration with Vladimir Jurowski and the ensemble United, and featuring songs written for him in the spirit of the Christmas season, in the Konzerthaus Berlin and in Düsseldorf. His performances as Faninal in Michieletto’s new production of Strauss’s Der Rosenkavalier at La Monnaie/De Munt in Brussels, planned for June 2020, were unfortunately cancelled due to the COVID-19 pandemic.
To kick off the 2020-21 season, Henschel is producing and performing in Così.20, a re-envisioned, contact-free and pandemic-friendly version of Mozart’s Così fan tutte as the premiere of his new opera company, Art House Opera, which he founded with Thomas Höft and their mutual artist collective during this time. The first performances took place in Lockenhaus, Austria, in the beginning of August.
