In 2015 the mezzo-soprano joined forces with director Karl-Ernst Herrmann to devise a staged recital – a journey not just through nature (the ‘garden’ of the title) but through the knottiest of emotional thickets, explored in solo scenas and cantatas by Handel, Leo, Vinci and Marcello. The staging may never have been completed but the project finds fresh life here in recital.

Handel aside, the repertoire is little-known. Kožená has chosen with care, presenting a really delectable selection of rarities that all make their case. The emotional range is exhilarating, taking us from the stately tragedy of Handel’s Ero –who, discovering her beloved Leandro dead, flings herself into the sea – to the pretty pastoral courtship of Leo’s Medoro and Angelica and the extreme unravelling of female despair in a lone aria from Gasparini’s Atalia.

Kožená is at her best in repose. There’s a fluidity and control to the exquisitely expansive central aria from Marcello’s Arianna abbandonata and a playful ease to the Leo that recall the mezzo’s earliest recordings. But Kožená’s soprano-coloured instrument offers less at moments of intensity, where it lacks breadth and depth of colour (especially at the bottom of the voice) and where vibrato tends to become agitated and uneven. It’s hard not think of all the other baroque mezzos out there who might bring greater colour and scope to these works.

Václav Luks and his Prague-based Collegium 1704 are exemplary collaborators, relishing the unexpectedly flighty, flirtatious string-writing of Vinci’s Sinfonia from Maria dolorata and the vivacious opening to the Marcello, always alive as accompanists to the shifting currents of these musical streams of consciousness.
