Born in Tandil, Argentina, María Cristina Kiehr has embarked on an international career since she moved to Europe to study with René Jacobs at the Schola Cantorum in Basel, where she still lives.
Her recording and concert activity is prolific, and she sings all over the world with most of the best-known conductors on the baroque scene and their orchestras. Examples include Frans Brüggen with the Orchestra of the XVIII century, Jordi Savall and Hesperion XX, René Jacobs and Concerto Vocale, Robert King with The King's Consort, Chiara Banchini and Ensemble 415, Chistophe Coin with the Ensemble Baroque de Limoges, Philippe Herreweghe, Gustav Leonhardt and Nikolaus Harnoncourt with the Vienna Philharmonic Orchestra and Concentus Musicus. She toured Australia with the Australian Brandeburg Orchestra and has been invited to perform with the Akademie für Alte Musik Berlin, Il Fondamento, the Norwegian Chamber Orchestra and the Gulbenkian Orchestra.
She is a co-founder of the vocal quartet La Colombina which specializes in Spanish and South American Renaissance Music and with whom she performs at major festivals throughout the world. She has also formed Concerto Soave, with harpsichordist Jean-Marc Aymes, focused mainly on early XVII century Italian music. Their recordings for Harmonia Mundi - Monteverdi's Pianto della Madonna, Canta la Maddalena, Scarlatti's Cantatas and Sigismondo d'India's Madrigali e Canzonette – all achieved great critical acclaim.
Her operatic repertoire encompasses works by Monteverdi (L’incoronazione di Poppea, Orfeo, Il ritorno di Ulisse), Telemann (Orpheus), Purcell (Dido and Eneas), Blow (Venus and Adonis), Glück (Orphée et Euridice), Vivaldi (Dorilla in Tempe), Cavalli (Giasone), Cesti (L’Orontea), and Haydn (Orlando Paladino); she has also recorded most of these works.
