How do artists gather discarded materials or ephemeral notions into a composition? This question is the jumping-off point for Goodman Gallery's collaborative group exhibition with blank projects, alluvium. Opening Thu, Sep 25. 

An interesting cohort of artists including Jared Ginsburg, David Goldblatt, David Koloane, donna Kukama, Laura Lima, Gerda Scheepers, Lerato Shadi, James Webb, and Clive van den Berg (whose retrospective solo Porous is also showing at Wits Art Museum) share space for alluvium – Goodman Gallery's collaborative showcase with blank projects.

This exhibition runs over Johannesburg's art season as one of the year's most anticipated fairs, FNB Art Joburg, takes over the Sandton Convention Centre from Fri, Sep 6 – Sat, Sep 8.

The title of the exhibition, alluvium refers to loose clay, sand, and earth that is gradually deposited by moving water, such as a stream. "With both galleries dedicated to a cross-pollination of artistic voices and building a resilient ecosystem, this show enacts the idea of collaboration as a practice," reads the exhibition statement. "Considering ideas around debris as the composition itself, the exhibition explores how artists can gather discarded materials or ephemeral notions into a composition. Through this, psychogeographic cartographies are formed, mapping out and remixing strategies for engaging with and interrogating the world."

The group show alluvium runs at Goodman Gallery until Sat, Sep 28. In the gallery's Viewing Room space, Banele Khoza's solo of watercolour paintings Things left unsaid shows until Thu, Sep 26.
