The result of the two-week residency was Terra Incognita, a piece for baritone singer and orchestra inspired by the ill-fated last expedition of Robert Falcon Scott.

Described as "a masterful portrayal of grief and desolation and one of the most moving tributes to those who lived through World War I", it also played as part of the New Zealand Festival in March 2016.

A new opera, it was scored by Farr and written by poet and playwright Renee Liang, and explored the mysteries, traumas and gifts of migration, home and belonging.

[11] Also in 2017, Farr worked on another NZSO commission, a substantial cello concerto titled Chemin des Dames, with a personal World War I connection.

"All three of my great-grandmother's elder brothers, beautiful young boys, were killed within a year in separate battles in northern France and Belgium".

The concerto premiered in New Zealand and France by cellist Sébastien Hurtaud,[12] recognising a shared wartime history.

[13] Alongside Jack Body, Gillian Whitehead and John Psathas, Farr is one of the noted New Zealand composers.

Since 1997, the cabaret Drumdrag features Lilith playing the drums and Farr has recorded a CD released under her name.

[16]In the 2006 Queen's Birthday Honours, Farr was appointed an Officer of the New Zealand Order of Merit, for services to music and entertainment.
