Big Mistake?

It would seem Natalie Imbruglia has a little sister, Laura, who is apparently releasing an album. What the fuck? I'm just listening to some of it from
her website, and though not particularly my cup of tea, it is apparently quite a good album.
I'm more intrigued however as to where she has popped up from. Has she been around for years, living in the shadow of Mrs Silverchair?
Further investigation (ie. a quick goooooooogle search) and I find she obvisoulsy has a myspace site which tells us:

'It Makes A Crunchy Noise' will be the debut EP for Laura. This Imbruglia doesn't sound anything like her big sisters pop pieces. We are talking indie rock here. She describes her sounds as "quirky electro-clash punk folk rock/pop on an acoustic guitar, Without the electro-clash part".

Well good luck to her. I just hope she doesn't try too hard to separate herself from Natalie by reminding us at every opportunity how rock she is man.
