Deadly Nannas (Nragi Muthar) is a musical group from Murray Bridge, South Australia, founded around 2016. The group of singer-songwriters is composed primarily of Ngarrindjeri women (with two kringkri ma:dawar, or white sisters), and performs as a vocal ensemble with a backing track. The group was formed in 2017 with the goal of writing and performing songs in Ngarrindjeri for the preservation and promotion of that language and culture. The women have all have completed a tertiary course in learning an endangered Aboriginal language, which helps them to use a fusion of Ngarrindjeri and English. Several of the Aboriginal members of the group grew up speaking their language at home, but not being permitted to speak it anywhere else. Some of the group were affected by the family break-ups cau
