The choir will present their modern choral music, which includes Anton Bruckner’s famous motet Vexilla regis and Francis Pott’s Balulalow on November 27.

Held at the Holy Trinity Anglican Church on Anson Street, the concert will also feature a performance of Gordon Hamilton’s Turing Believes Machines Think.

Mr Hamilton’s piece is from a letter by computer pioneer Alan Turing, who was instrumental in developing the Nazi code-deciphering Enigma machine, but prosecuted for his homosexuality. 

The British mathematician signed the letter with a syllogism, expressing his fear that his life’s work would be overshadowed by or even disproven due to his charge for ‘gross indecency’.

"Turing believes machines think / Turing lies with men / Therefore machines do not think / Yours in distress, Alan,” he wrote.

The concert will also feature works by Sean O’Boyle, Cathy Milliken and Melbourne-based Lisa Young, known for her blending of jazz, a cappella and Indian vocal percussion styles.

Known for their quirky appearances online, The Australian Voices made international headlines in 2014 with a video of Rob Davidson’s Not Now, Not Ever!, a musicalisation of Julia Gillard’s misogyny speech.

Their 2012 album for Warner Classics was observed by Gramophone Magazine to "boast a crisp, resonant delivery of the sonic goods” while a writer for Limelight Magazine described their show as “the finest choral singing that I have ever heard in Australia.”

Recently the group has brought their distinctly Australian sound to audiences in Guatemala, Mexico, China, the UK, Germany, New Caledonia, USA, Palestine, Woodford Folk Festival and Hobart Festival of Voices.

Tickets to the upcoming tour of Orange, Armidale, Mudgee, Lithgow and Canberra include an optional workshop.

Attendees will rehearse a piece with The Australian Voices, learn choral singing techniques from conductor Gordon Hamilton and join the group in concert.

Tickets are available through The Australian Voices website.
