Rättö Ja Lehtisalo is the project of Finnish musicians Mika Rättö and Jussi Lehtisalo, who can be associated with acts like Circle (!!!!!!!), Moon Pharaoh Overlord, and others. UU Mama is their fourth full-length, as far as I'm aware, and there was just a new release by the duo this year.
This is pretty much a mixed bag. Although there are elements of the folky, psychedelic, and daring electronica, one might describe their music as just catchy pop (or something closely related). From what I translated of a certain review, they consider Kraftwerk to be an influence? Not important. It's Finnish, which already adds a degree of unusual atmosphere to the listening experience.
