Painting is a fight and few artists demonstrate this more emphatically than the volatile and complicated post-war master, Joan Eardley. Scotland’s great English artist or England’s great Scottish artist, box her as you will, she’s revered north of the border, but often oddly dismissed south of it. The Scottish public have been enthralled by her work for decades, and spoiled in their access to it, with 60 or so pieces in the National Galleries of Scotland collection alone (the Tate has just one).
