Angus & Julia Stone are an Australian brother-sister duo that I first heard when their song "For You" was heavily featured in the pilot episode of Revenge. While I haven't kept up religiously with that show over the past few months, I have continued to listen to the music of the siblings Stone. Considering how distinctive their voices are, I love how they are still able to create variety within their music. I imagine numerous hipsters are driven to Angus & Julia Stone because of their folksy sound and grungy visuals, although don't let that dissuade you from listening to them.
I have attached a few of my favorite songs to this post; "Just A Boy" features Angus on the lead vocals, while "And The Boys" features Julia. Both are wonderful, in my opinion.
