The American soprano and voice teacher, Klesie Kelly [Klesie Kelly-Moog], studied voice in Germany with Bettina Björgsten, Helmut Kretschmar and Günther Weißenborn.
More active in concert than on the opera stage, Klesie Kelly has collaborated with conductors such as Moshe Atzmon, Wolfgang Gönnenwein, Erich Leinsdorf, Bruno Maderna and Hiroshi Wakasugi. In 1971, she appeared at the Mozartsaal of the Konzerthaus in Vienna, singing Lieder by Purcell, Schubert and Strauss, among others, accompanied by Norman Shetler. She recorded songs by composers including W.A. Mozart, Robert Schumann, Wolf and Zemlinsky with pianist Werner Genuit. In 1977, she recorded evening songs and love songs (Abendlieder, Liebeslieder und Romanzen) with tenor Ian Partridge, accompanied by instrumental soloists including Hermann Baumann (horn), Dieter Klöcker (clarinet), Karl-Otto Hartmann (bassoon) and again Genuit. The selection of rarely performed chamber music includes Schlummerlied (slumber song) by Benedict Randhartinger (Germany) for soprano, tenor, horn and piano, Franz Lachner's Seit ich ihn gesehen (after Chamisso) for soprano, clarinet and piano, and his Laute Liebe (noisy love) for soprano, bassoon and piano.
In Wiesbaden, Klesie Kelly sang with the choir Rheingauer Kantorei, both in 1979 Felix Mendelssohn's oratorio Elias with the Radiosinfonieorchester Frankfurt alongside the bass-baritone Erich Wenk in the title part, and in 1980 Arthur Honegger's König David, with Claudia Eder and Gerd Nienstedt as the narrator.
