Feldberg is the combo of Eberg's orchestrations and the vocals of Rosa Birgitta Isfeld. The two were writing songs together for months in their home of Iceland, and came up with a few good hits including "Dreamin" that they released in 2009 which went on to success in their hometown. Since Eberg had already built a fan base in the UK with his solo dream pop music, it was a no brainer that the pair sing in English to appeal to a wider audience. Isfeld's soprano voice corals the listener through various upbeat electro tunes that also feature a wide array of acoustic instruments.
