Ngā Tai Hurihuri (The Changing Tides) was a commission by the New Zealand arm of Accenture to commemorate its re-branding. The brief for the commission was to create a work expressing renewal through the new ways of doing things working in partnership with the old. The work was written especially for the operatic soprano voice of Deborah Wai Kapohe and kaikaranga Aroha Priest – the soprano metaphorically representing the new ways and the kaikaranga representing the old. As well as including solo marimba, maracas, bongos, cymbals and tam-tam, the percussion set-up includes two stations of tom-toms arranged in a mirror image of one another to exploit the choreographic potential of two drummers playing in unison.
