A review in the FAZ by Holger Noltze translates to: With clear articulation, great eloquence and the necessary resources Christiane Kohl met the demands of the role, continually switching through all the shades between parlando and singing, and between a well-judged bitchy tone and finely shaped lines.In 2008, Kohl recorded in the Frauenkirche Dresden the Christmas oratorio of Gottfried August Homilius, with Annette Markert, Marcus Ullmann, Tobias Berndt, Sächsisches Vocalensemble and Virtuosi Saxoniae, conducted by Ludwig Güttler.
[3] In the 2009-2010 season, she sang as a guest artist at the Kiel Opera House as Hanna Glawari in Die lustige Witwe.
