Check out Toni Collette's new CD, Beautiful Awkward Pictures. You can hear the songs at her web page and watch a video of the title song at YouTube. I read that is was only being released in Australia, but I downloaded it from iTunes.
I found some information about her singing background. She has been singing since she was 14: school musicals, the lead in a big musical production celebrating the bicentennial, advertising jingles, musicals in Sydney and on Broadway. She's been writing songs for about ten years.
Her husband, Dave Galafassi, is the drummer in her band.
