Free Exhibitions in London

"Inside, you are plunged into near-total darkness, feeling your way along softly curving corridors lined with compact, hair-like roots. And unlike the dank, musty odour one might expect from a mound of soil, Morelos' beast smells unexpectedly good: infused with clove and cinnamon and softened by the cool scent of earth after rain."

"For the past 50 years, Hockney has flitted between these two modes, returning occasionally from noodling to remind us of his gift for direct communication (see his portrait of the performer Divine, the affecting drawings of his ageing mother, or his paintings of the Yorkshire landscape in the 2000s). But, sad to report, it is to the late stages of the jazz tendency that most of this exhibition belongs."

"I've never been a huge Baselitz fan: I found the whole upside down painting thing an affectation and I would have happily fronted a campaign to have all his work shown the right way up so we can see what it's really about. I also think he churned out the same painting for decades. But this is brutally emotional stuff."

"And she is magnificent — not merely critically, but commercially. Brown is among the most expensive living female painters in the world, her canvases commanding prices that would make lesser talents weep. The market, for once, is not wrong."

"Certainly, blockbusters showing Van Gogh have the most populist pulling power, but credit is due to the National for truly seeking to provide a fuller geographic and historical view of other artists and movements. To this end, this Waldmüller showcase is the art historical equivalent of eating your greens: it may not quicken the heartbeat but is nonetheless a healthy exercise forming a fully balanced palate."

"These were revolutionary photographs at the time – and they still feel new in their search to express the inexpressible. The dimly lit, subterranean gallery keeps you cocooned in this elegiac, brooding atmosphere. Kawada is drawn to images that trace the extremities of the Earth, the visible outer edges of our existence – the sky, the horizon, water, burning suns and scorching fires."
