Warner was an aspiring bluegrass musician (which was unusual in Australia at the time) after inheriting the music from his father, an early Australian bluegrass pioneer.  The winner of the Australian National Bluegrass Mandolin Championship for four consecutive years, Warner had toured with country music artists Gina Jeffreys, and with Young again in Kasey Chambers's band.  Before the band formed, Carol Young and Warner both knew each other, and according to Warner had been drawn to bluegrass and American roots music through an appreciation of George Jones and Merle Haggard.  After meeting, Warner and Young made the decision to emigrate to America, to pursue musical careers there.  Later, Young and Warner were living together in Sydney, and trying to find work in the moribund Australian bluegrass scene.  After leaving Australia, they spent time in West Texas before relocating to Austin.
