Kaja的第三张也是最新专辑，发行于2013年10月。在这张专辑中，乐团更注重于东欧与北欧民谣的结合，音乐整体更趋成熟。瑞典的乐评界普遍认为：在这张专辑中Kaja将自己独立的音乐风格得到了更好的体现。 Kaja’s latest release - Tre Trappor Upp – treats you to their own particular brand of daring and dazzling chamber folk, full edgy twists and turns. Always partial to East European folk music, over the past ten years Kaja has also forged their own musical language by layering on more and more dimensions. Their eclectic blend has evolved into a genre of its own: A fusion of klezmer, tango, Swedish traditional, French waltzes, cinematic art music and improvisation spiced with fresh influences from American folk music, acoustic club music and Indian ragas. Building on the strengths evident on their critically acclaimed second album, Rust, their sound has continued to mature and more space has been given to improvisation. The magical sleeve art is the work of Yusuke Nagano. And if you buy the LP version of Tre Trappor Upp, you will also get nine poems – one for each track – written by the uniquely talented Olivia Bergdahl.
