As the '90s became the 2000s, two bubbly teenagers came seemingly out of nowhere to score back-to-back top 5 singles, "Sister" and "What's A Girl To Do", but Christine and Sharon Muscat had been preparing for that moment for years. First, growing up with their musician father, Joe, helping them to develop their talents and then, being spotted by Tina Arena on TV and signed by her then-husband/manager, Ralph Carr. Sister2Sister were quickly launched overseas, with UK chart success and key support slots on tours by Five and Britney Spears. But the pop stardom ended just as suddenly and a planned (and recorded) second album was never released. The sisters talk about the decisions they made following the release of their debut album, One, that changed the course of their joint career. Over the past two decades, the siblings have worked in a more behind-the-scenes capacity as session singers, backing vocalists and vocal coaches, but they are set to release their first music as Sister2Sister in two decades and explain why they feel lucky to have had the experience in the music industry that they've had.
