David Koch presents the hot new show that sees choirs from around Australia stand and deliver. Prepare to hear what you've never heard before as choirs are challenged to perform songs from the likes of Powderfinger, Kylie Minogue, Rihanna, AC/DC, Scissor Sisters, Pink and more. The judges, including tenor Jonathon Welch, Australian music icon Iva Davies, entertainer and actress Charli Delaney, and one of Australia's most sought-after choral conductors George Torbay, will have full say on who makes it through each round of the knockout competition, with two choirs eventually going head to head in the grand final.
