Seba Calfuqueo. Cautin

In a 3D animation, the artist's mother, Carmen, travels the Cautín River with whales beside her: Trempulkawe, beings from Mapuche tradition that carry souls after death. Seba Calfuqueo, a Mapuche artist born in 1991, made the 25-plus works new for her first solo show in Europe.

You walk it against the current, from the Pacific up to the river's source at the Lonquimay volcano, and the route ends on a video of the artist curled in a fetal position. On the way are twelve glazed ceramics crossing a Mapuche vessel, the metawe, with river animals such as Darwin's frog, embroidered paintings you can see from both sides, and a six-metre mural. The rooms are done in kalfü, the Mapuche sacred blue.

It fills the temporary rooms on level -1. Entry is free on Mondays 12:00 to 16:00 and Saturdays 21:00 to 23:00, with night walkthroughs on 24 October and 21 November. Madrid's Manzanares is mostly famous for being small; this river gets followed from the sea to a volcano.
