Perhaps it was the nymph-like sculpture high above the River Frome, which runs alongside Iford Manor, that inspired Iford Arts to make Dvorak's Rusalka its first in-house production. It was certainly an apt choice for the tiny cloister in Harold Peto's wooded garden, where streams abound and water sprites might linger. The choice of director and conductor was also inspired. Jeff Clarke and Oliver Gooch conjured a magical atmosphere, scaling the opera to chamber proportions with such a sure touch as to make one feel disinclined to watch a full-scale production again.

The idea of Dvorak purely as a symphonist disregards the often extreme delicacy of his writing. Here, Iain Farrington's arrangement was faithful to the spirit of Dvorak's instrumentation, with flute, timpani, harp and horn bringing an impressionistic shimmer. Gooch also let the recurring motifs reveal the composer's astute characterisation.

Yvette Bonner was perfectly cast in the title role: a petite, alluring figure whose gliding and insinuating movements were sensuously graceful. Her voice, by no means massive but clear and true, always expressed Rusalka's anguish, first aspiring to human love and then, when it fails, resigning herself to fate, condemned to haunt the prince she adored. Julian Close's imperious Water-Gnome and Philip O'Brien's Prince were also strong, while Helen Johnson's witch Jezibaba was all the more ominous for being a Dr Jekyll figure. The surgery to remove Rusalka's scales was just one of the clever details from designer Elroy Ashmore, making so much more than a woodland idyll.
