An award for artists whose work engages with "social reality, lived experience and the human condition" has been won by a Mexican forensic technician whose works deals intimately with her country’s brutal drug wars. Britain’s most valuable art award to a single artist, the Cardiff-based Artes Mundi Prize, saw nominees this year from Cuba, England, India, Lithuania, Slovenia and Sweden. But the winning works by Mexico’s Teresa Margolles were the ones that responded most directly and dramatically to the competition’s challenging premise.

National Theatre Wales like the word “us”. It was there in Michael Sheen’s Passion of Port Talbot – its film adaptation was called The Gospel of Us – and it is here, prominently, in the multi-layered title of Mike Pearson and Mike Brookes’ latest site-specific offering. The team that brought Aeschylus’ The Persians to the Brecon Beacons military range have now commandeered a disused aircraft hangar a few miles outside Cardiff to stage an experimental version of Shakespeare’s Coriolanus, sprinkled with Bertolt Brecht’s unfinished version Coriolan.

It was one of the better Olympic culture ideas that Wales, Scotland and England should combine in a Dance GB night, with the three “national” dance companies all creating something new. But a risk that had little Wales holding its breath in fear, up against the might of English National Ballet and Scottish Ballet. And who would have expected the 12-strong National Dance Company Wales to emerge as unexpected heroes?

This Friday afternoon at five o’clock, the National Poet of Wales Gillian Clarke will recite a new poem and initiate a seismic week of Welsh cultural exploration. The inaugural Dinefwr Literary Festival will bring writers and musicians from Wales and beyond to a National Trust house and park in Carmarthenshire. Unlike other literary festivals in Wales – notably Hay and Laugharne – this one will straddle the border between English and Welsh.

To each their own Hay. The Roman encampment that is the modern-day literary festival, circled by pantechnicons and trending in the Twittersphere, looks very much like a monomaniacal content provider for all comers. Astroturf walkways deliver the cagouled hundreds and thousands to events in tents with clockwork regularity. But the reality is, of course, that no two experiences of Hay are alike. A bit like snowflakes.

Apart from “I did not have sex with that woman” and maybe “It’s the economy, stupid”, Bill Clinton seems never to have said anything quite as memorable. Indeed, of all the phrases with his name attached, none is quoted quite so tremulously as Clinton's description of an event that takes place annually on the border between England and Wales as May makes way for June.

Ever since the Polish photographer Maciej Dakowicz documented the debauchery of South Wales nightlife in a series called Cardiff at Night, there has been a kind of perverse glamour in images of scantily clad girls and young women falling down drunk whilst roaming gangs of check-shirted “roiders” look on gormlessly. Being as Swansea’s nightlife is, as depicted here, even “scruttier” – to use the evocative local parlance (think “slut” meets “scrubber” and you’ve got it) – than that of the capital, an artistic documentation of Swansea at Night was inevitable at some point.

Looking at CCTV footage of a school hall in Cardiff through Adobe Flash Player in the corner of a webpage and listening to the attendant interference, bells, buzzes and bleeps might not sound like the cutting edge of theatre. But by the time National Theatre Wales’ tech wizard Tom Beardshaw closes the live stream of Tim Price’s electric new play The Radicalisation of Bradley Manning with the school pupils and soldiers we have been watching taking their bow, this is exactly what the "audience" are convinced we have witnessed.

The Laugharne Weekend has become a fixture in the crowded calendar of festivals that now punctuates not just high days and holidays but the whole six months that make up British Summer Time. Carving a niche for itself as a halfway house between literature and music, Laugharne’s success is built on two key factors.

Like many students, I read the Oresteia by Aeschylus as an undergraduate as part of a compulsory Tragedy paper. A while ago I was asked would I do a new version of the Oresteia. I’m not a Greek scholar so I feel I have no authority to offer a "translation". However, I was up for writing a completely new play.
