ROSIE is the forthcoming debut EP from an 18-year-old singer-songwriter from Brisbane who has cast a spell on all in her path since her first demo, FATHER SAID, won Triple J's Unearthed competition in July 2012.

Led off by the sunny burst of self-assertion AROUND HERE, the six songs reward months of anticipation in the musically muted, lyrically forthright style that's made Thelma Plum such a compelling new voice.

Between the long-distance lilt of the title track (that's "Rosie" on the cover) to the hard-won resilience of the string-laden BREATHE IN, BREATHE OUT, ROSIE is a rare instance of an artist arriving fully formed on the public stage. Which begs the question. Where did this extraordinary voice come from? "Mum says I was singing before I could talk. I lived on my grandparents' farm in Delungra (northern NSW) for a while and my grandfather used to play the harmonica and teach me the piano and listen to his wireless at 4am. Hank Williams, Slim Dusty, old country music . . . we were huge Kasey Chambers fans.

"Paul Kelly is my earliest memory of hearing something and thinking, 'I love that so much, I wonder if I could do that?' Mum took me to see him play with Leonard Cohen at Brisbane Entertainment Centre. I remember thinking, 'Yeah. I want to tell stories like that'."In 2011, Thelma was in the first intake of students to graduate from Music Industry College, a senior high school in Brisbane's Fortitude Valley. She cut her teeth performing and serving in Gold Coast cafes, where she clicked with a star barista named Andrew Lowden who happened to be a muso as well.

The immediacy of their chemistry is perhaps best illustrated by the EP's final track, KING, which was co-written over a backstage piano in a matter of minutes last September, just before Thelma took the stage to accept the Sydney Opera House Award for emerging talent at the 2012 Deadly Awards.

In between the Triple J Unearthed win and her finalist nomination in the J Awards, there was also the National Indigenous Music Awards in Darwin, where Thelma joined the Medics and Coloured Stone's Bunna Lawrie for a rollicking take on Bob Dylan's "Blowin' In The Wind".

In November, her cult went global when FATHER SAID was celebrated on the UK-based Record of the Day blogsite. In December, Shane Howard invited her to join his 30th anniversary celebration of "Solid Rock" at Melbourne's Forum Theatre. In January, she drew her largest audience so far at the Woodford Folk Festival, and sealed months of relentless record label attention by signing to Warner Music's Footstomp imprint. ROSIE was written and performed by Thelma and Andrew, and produced by Tony Buchen (Tim Finn, John Butler, Washington) at Sydney's 301 Studios. "It was a collaborative process with Tony and Andrew, not just me saying 'This is what I want'. The whole last year has been such an incredible learning curve in that way. But the songs come pretty easy, mostly. They're all really special to me. They come from my life."
