Kurva Choir is an experimental chamber orchestra, comprised of C.J. Boyd on bass and voice, Molly McDermott on cello and voice, and Dominique Hamilton on viola and voice. C.J. releases solo music on Joyful Noise Recordings and has collaborated with musicians as diverse as Chris Schlarb, Helena Espvall, Andrew Weathers, and Eliot Lipp. Molly also plays in the folk duo Evan and Molly (along with Evan Phillips of The Whipsaws).
The group grew out of the open-ended improvisational project Kirtan Choir (formerly The C.J. Boyd Sextet), which included such come-and-go members as Nat Baldwin, Jessica Pavone, Larkin Grimm, Valerie Kuehne, as well as members of Ra Ra Riot, Paper Bird, Balmorhea, and The Ascent of Everest.

In February 2013, Kurva Choir released the album ‘understory’. It was followed in December 2013 by the EP ‘Archaea’.

In 2014, Kurva Choir contributed a cover version of Breathing to the album Running Up That Hill: Kate Bush Covers For Reproductive Rights.

It was followed in 2015 by three albums: ‘A Scourge of Small Cords’, ‘Ways Where Mountains Were’ and ‘Deep In The Outside’.
