That experience served Kenny well when the recession of the early '90s crimped British arts scenes; she moved to Paris and won a place in the pioneering Baroque ensemble Les Arts Florissants, led by American-French director William Christie. The Baroque, especially in its irregular and imperfectly understood English varieties, has remained her main focus, although she has enthusiastically played Renaissance music as well. Kenny remained with Les Arts Florissants from 1992 to 2007 and then joined the Orchestra of the Age of Enlightenment, performing with that group from 2007 to 2015. She made numerous recordings with both groups and has continued to collaborate with them on new projects. Kenny has also accompanied Ian Bostridge and other singers on recordings.
Her own solo career has been marked by recordings of little-known repertory and might be placed in the specialist category if they did not astound with sheer virtuosity. She has recorded with her own group, Theatre of the Ayre, mostly for the Linn label. The group's recording of John Blow's Venus and Adonis was issued by the Wigmore Hall Live label. In 2017, Kenny released The Masque of Moments, an exploration of the music of the 17th century English masque, based on a touring show Kenny had developed for Theatre of the Ayre some years earlier. A professor at the University of Southampton, Kenny has also taught at the Royal Academy of Music and at the Hochschule der Künste, Berlin. Her teaching has been marked by unusual enterprises such as the assembly of 360 child ukulele players with whom she investigated the connections between early music and the blues. ~ James Manheim, Rovi
