Oh Pep! are an Australian band formed in Melbourne, Australia by Olivia Hally (vocals, guitar) and Pepita Emmerichs (violin, mandolin). Their debut album, Stadium Cake, was released on 24 June, 2016.
The duo met at the Victorian College of the Arts Secondary School in 2009, and began writing songs together. In mid-2011, their musical duo, known as Oh Pep!, expanded into a five-piece lineup with Stuart West (double bass), Paddy Montgomery (mandolin, bouzouki) and Justin Olsson (drums, percussion). The band’s line-up has changed several times since, with Hally and Emmerichs the constant factor in all line-up configurations.
