Courtney Barnett is one of the most important songwriters of a generation.

Songs like 'Avant Gardener', 'Depreston' and 'Pedestrian at Best' find joy in the mundane and have taken Courtney's self-deprecation, dry sense of humour, and playful storytelling to an international audience.

Courtney Barnett’s story is entwined with that of Milk! Records, the label she founded from her Melbourne bedroom back in 2012 to release her first EP I've Got A Friend Called Emily Ferris.

Digging into a decade of interviews, live performances, albums, EPs and B-sides, The J Files charts the stratospheric rise of this singer songwriter and finds out what the next chapter holds.

We’ll also hear from Milk! Records label artists Jen Cloher and Fraser A. Gorman, as well as filmmaker Danny Cohen, musicians Kim Deal, A.C. Newman, Darren Hanlon and Sibylla Stephen (The Little Stevies).
