The Belton, TX-based heavy rock quintet Flyleaf formed in 2000 when frontwoman Lacey Mosley tried out a string of the dark, hard-edged songs she consistently wrote as a brooding teen on drummer James Culpepper. After a brief period of playing together, they recruited guitarists Sameer Bhattacharya and Jared Hartmann, members of a local outfit that had recently called it quits. In 2002, bassist Pat Seals joined, and the band, initially known as Passerby, was born.

The moodiness befits Mosley's background: as one of six siblings in a single-parent household, the confessional songwriter spent her childhood moving from apartment to apartment whenever the bills went unpaid. She openly acknowledges an early addiction to drugs and alcohol that fueled bouts of depression. As of the release of Flyleaf's full-length, the band was committed to sobriety.
