One time a friend asked me to go to see/hear Brooke Fraser (or Ligertwood as she's known now she's married) in concert, as had a free ticket. I'm not a fangirl but her songs are not too bad. They're catchy. I wasn't able to go though as she sort of sprung it last minute on me on the day and I was busy doing something else, and wasn't able to get there in time.
She's famous for Something in the Water, What to do with Daylight, and What a Beautiful Name
I think what makes her stand out from the rest is her voice, I instantly recognise it's her, and the music has more melody in it, and interesting lyrics, although the Hillsongs are a bit repetitive.
