Marewrew has been played on NTS shows including The Do!! You!!! Breakfast Show w/ Charlie Bones, with Kane Ren Ren first played on 19 September 2015.

Marewrew (マレウレウ), meaning ‘butterfly’ in the Ainu language, is a group of female artists working on the diffusion and renewal of the upopo songs of the Ainu people of northern Japan. In 2010, after launching their first mini-album "MAREWREW," they started full-scale activities and were brought to the attention of local and international audiences thanks to their performances at the international world music festival Womad (UK) and other European venues. Their work, which incorporates a modern arrangement of upopo songs, has been highly praised.
