Anna Gebert shapes her teaching with a great deal of empathy and a holistic understanding of human psychology. The experiences of each person and their individual paths are to be taken into account as well as the questions into which we must first live:
“Be patient toward all that is unsolved in your heart and try to love the questions themselves, like locked rooms and like books that are now written in a very foreign tongue. Do not now seek the answers, which cannot be given you because you would not be able to live them. And the point is, to live everything. Live the questions now. Perhaps you will then gradually, without noticing it, live along some distant day
into the answer.”
― Rainer Maria Rilke

Voice
María Cristina Kiehr
September
The Argentian soprano, Maria Cristina Kiehr, born to Danish descendents, received her early musical training in Argentina. She studied the violin as a child, in the city of Tandil in Argentina, but at the age of 17, she discovered her soft, amazing soprano and her love of Baroque music. The discovery led to a fast change: After only a year of singing lessons, in 1983, she went to Europe, to the leading institute in the revolution seeking authenticity in the performance of Early Music: the Schola Cantorum Basiliensis, and studied under René Jacobs. Later she said: “he is the musician who has had the most influence on me”. At the same time she took courses in vocal technique with Eva Krasnai.
​
Maria Cristina Kiehr is an all-European artist, and Switzerland is still her home. Kiehr is married to a cellist, Orlando Theuler. From Basel, she travels to performances in many countries, with the best conductors in the field. She is incontestably one of today’s leading vocal artists in the field of Baroque music and has appeared throughout the world in concerts and recordings with celebrated conductors, like René Jacobs, Jordi Savall, Nikolaus Harnoncourt, Philippe Herreweghe, Frans Brüggen, Gustav Leonhardt, Konrad Junghänel, and with orchestras and ensembles specializing in the Baroque music field, as Concerto Vocale Leipzig, La Fenice, Cantus Cölln, Ensemble Vocal Européen, Hespèrion XX, Elyma, Nederlands Kamerkoor, Concerto Köln, Ensemble 415, etc.
​
Maria Cristina Kiehr is particularly interested in early Baroque music. She is co-founder of the ensembles “La Colombina”, “Daedalus” and “Concerto Soave”. From the start of her career, she was attracted by integration as a singer alongside other singers and musicians, within the polyphonic texture. Later she moved to a somewhat different phase, and is turning more to the solo route.
​
In 1988 Maria Cristina Kiehr made her opera début in Innsbruck in Cavalli’s Giasone under René Jacobs. She has also sung in L’Incoronazione di Poppea, Orontea, and Dido and Aeneas (Purcell) under René Jacobs, Dafne (Gagliano), L’Orfeo (Monteverdi) and Il ritorno d’Ulisse in patria (Monteverdi) under Gabriel Garrido, as well as the title role in Dorillo in Tempe (Antonio Vivaldi) under Gilbert Bezzina and Il schiavo di sua moglie (Provenzale) under Toni Florio. Her operatic repertoire encompasses also works by Georg Philipp Telemann (Orpheus), Blow (Venus y Adonis), Glück (Orphée et Euridice), Cesti (L’Orontea), Haydn (Orlando Palladino); she has also recorded most of these works.
​
Maria Cristina Kiehr sang the part of Mary Magdalen in Antonio Caldara’s oratorio Maddalena ai piedi di Cristo and took part in the new recording of Monteverdi’s Vespro della Beata Vergine, both under René Jacobs, and both of which were greeted with universal acclaim.
​
One example of this new career path is a wonderful CD containing motets by Monteverdi, “Pianto della Madonna.” Another example is her new CD, with the same musicians, devoted to Sicilian composer Sigismondo D’India, also from the early Baroque period

Bandoneon
Maxime Point
August
Maxime is just as ease playing in a big orchestra as he is with a small group of musicians. He continues to push his work further and further, probing tango and exploring various forms of improvisation… and composition too. He is fond of the relationship he has with tango dancing and with the dancers onstage. Certain projects he collaborates on require the musicians to become actors and to develop their stage presence. Maxime enjoys this challenge, and is involved both in theatre andperformance art. He likes playing offbeat music, whilst keeping a traditional touch to hisstyle.
Maxime’s craving to play with other musicians and to explore other artistic spheres, combined with his sensitivity to the world around him, makes his music poignant and radiant.
Born in 1983 in Puy en Velay (France), Maxime began playing music at the age of six. He started playing the accordian when he was seven. At the age of eighteen he discovered tango and the bandoneon, thanks to Hervé ESQUIS. He immediately felt that this form of music and this unusual instrument were both absolutely essential to him as a musician.
He continued studying music at Saint-Etienne’s music academy alongside Philippe BOURLOIS, the two men forging a close relationship throughout Maxime’s music studies and right into his professional career as a confirmed musician. He obtained his music diploma (DEM) and went on to be nominated as laureate in 2009 amongst the gold medalists before perfecting his music studies with an advanced diploma in 2010.
He then continued training in musicology, music analysis and composition, and he wrote a dissertation on Igor STRAVINSKY'S «Rite of Spring».
Maxime has participated in Master Classes with renowned musicians such as Daniel BREL (Bandoneon / Tango), William SABATIER (Tango / Bandoneon), Marcel LOEFFLER (Jazz / Accordeon) and the internationally renowned accordeon concert artist, Yuri SHISHKIN.
He has also performed in "The Threepenny" Opera (Kurt WEILL) at Tours’ Grand Theatre.
For four years he played the accordion with the group DoÏna Quintet, performing jazz, klezmer, tango and improvised music. They released an album in May 2011 : "Cerno More".
Maxime has been playing the bandoneon with the group "Roulotte Tango" since 2006, directed by Julien BLONDEL. With them he has toured abroad to Germany, Turkey, Switzerland, Italy, Spain, Belgium, Russia, Luxembourg and the overseas territories of France. As a member of the group "Roulotte Tango", Maxime regularly collaborates with tango dancers. In 2011 he travelled to South Korea with the dancer / choreographer Odile GHEYSENS/in-SENSO to perform an improvised danse and music piece: "PAVOT Tango Addict".
He played in the "Gran Tipica Paris" with the pianist Roger HELOU and performs with thevery in-vogue tango orchestra, "Silbando".
Maxime is in a new project the "Cuarteto Entre Dos", for milongas and concerts (France, Poland and Italy).
