Here's another great band hailing from Sweden, Dag for Dag (with two dots over the "o").
They are a two-piece band from Stockholm. Comprised of two siblings (Sarah Parthemore Snavely and Jacob Donald Snavely) who were separated and then left to search for eachother their whole lives.
Hop over to their site http://www.dagfordag.com/ for their full story, photos, videos & more!
Their debut album, Boo was released in February digitally everywhere.
The guitar, the piano and both vocals, gives the album an overall dark, heavy and melodic tone that I can't stop listening to from beginning to end!
