'Barbara Nicholls: Sedimentary Flow' is the first substantial publication on the British artist Barbara Nicholls, who has been producing work for over 30 years. The title focusing on Nicholls' monumental watercolour works. These paintings emerged by manipulating the behaviour of pigment in ever-increasing quantities of water. As such their production remains consistent with Nicholls' approach to art production over the years, when she has stitched, drawn, covered, cut, built and otherwise extracted her media from sites of chaos. The book includes a specially commissioned essay by Martin Holman, whose writing on contemporary and modern visual art has appeared in leading art press outlets since 1979. He is a regular contributor to international media outlets such as Cura, Freize, Art Review and Art Monthly. His essays analyses Nicholls' watercolour works as well as the history of her practice prior to their creation. Holman's previously work about Nicholls appeared in the catalogue for Et in Arcadia Ego-Weltchaos cIdylle, Museum Kurhaus Kleve, Germany 2015. Barbara Nicholls lives and works in London.
