The artist Bill Viola died, after a long illness, early in the morning of Friday 12 July. I had the privilege of getting to know him while making a documentary about his life and work in 2001-2003. He quickly became a friend, as did his wife Kira and his sons, Blake and and Andrei. He felt like a kind of brother, who’d grown up through the same changes that shook culture up in the 1960s and 70s. Although he was American, I felt that we spoke the same language.

Under the guidance of director Ralph Rugoff, the Hayward Gallery seems hell bent on reducing art to the level of fun for all the family. And as though to prove the point, cretinous captions strip the work of all meaning beyond the banal, while press pictures showcase kids gazing at large sculptures.

Water glassily reflects in a bridal train, the sun moves between trees, giving way to metal book-leaves, and inside a warehouse so vast he cycles through it, stored cliffs of Anselm Kiefer’s work loom over him. Wim Wenders’ 3D cameras bring you inside the artist’s monumental, mythic world, which he is uniquely equipped to comprehend.

Always Open Always Closed is Caitlin Merrett King’s first published work of fiction, and it begins paratactically, with a list of displacements:

As a child, Anselm Kiefer tells us, in a bombed out German city, he would play in the rubble, creating life out of ruin and destruction. As an artist who is remarkably consistent, without being predictable, he continues to play in the ruins, breathing new life into the detritus of the world as well as his own collection of found objects, waste materials and other elements from which life appears to have been sucked out by time and history.

The artist Brian Clarke, surely one of the leading British artists of our time, has been all too readily dismissed as a mere craftsman. So much for being an outstanding and highly original painter who’s also done more for contemporary stained glass than any other artist in the world.

His ability to transcend boundaries and follow his own path rather than court marketable fashion and fame, has led to him being side-lined and ignored when he should be celebrated as vigorously as David Hockney and other art world giants of his generation.

Sophia Giovannitti begins selling sex because it promises to make her the most amount of money in the shortest amount of time. She also has a “near categorical hatred of work.”

Who created the term “electronic superhighway”? First described a system of linked communication that would become the internet? Envisioned a multichannel TV system where viewers chose for themselves what to tune into? Watch Amanda Kim’s excellent documentary Moon Is the Oldest TV and you find that the correct answer to all those questions is Nam June Paik.

Benvenuto Cellini’s My Life (1728) is not the artist-biography to which Susan Finlay’s The Lives of the Artists pays its most obvious homage, but it appears to have followed its advice. All men of achievement and honesty, Cellini argues, "should […] write in their own hands the story of their lives, but they should not begin such a fine undertaking until they have passed the age of forty."

Entry to Mike Nelson’s Hayward Gallery exhibition is through what feels like the store room of a reclamation yard. Row upon row of Dexion shelving is piled high with salvaged building materials including old doors, ancient floorboards and wrought iron gates, while even more gates and doors are leant against the walls.
