A dark night of the soul gets mined for maximum effect in Irish director Lenny Abrahamson's third film, a subdued yet infinitely disturbing portrait of a teenager, and by extension his community, undone by a sudden act of violence. Set among Dublin's comfortable Sandymount middle-class, the film couples an improvisatory vibe with a gathering sense of grief that brings Greek tragedy to mind. And when the movie's deliberately clamped-down feel cracks open, watch out: the howl it unleashes is terrifying to behold.

“It’s always the quiet places where the mad shit happens,” observes Garda Lisa Nolan (Ruth Bradley) in Northern Irish director Jon Wright’s creature feature. And, credit where it’s due, the mirthfully monikered Grabbers presents us with some classically mad shit. Set on the fictional Erin Island - a fishing village off the coast of Ireland - Grabbers is Wright’s second feature after 2009’s Tormented.

On Sailing to Byzantium Christine Tobin's utterly singular music fuses with the amaranthine force of WB Yeats's poetry to create one of the most transporting jazz releases in aeons. From the iridescent colours of “The Wild Swans at Coole” and the statuesque tranquility of the title track, to the subtly ornamented melodic line of “The Song of Wandering Aengus” and the deeply poignant “Long-legged Fly”, the album's unique sound-world and intense depth of feeling completely seduce the senses.

Sligo Live is Europe’s most westerly music festival, and its mix of indie and traditional is unique. For four nights and days, cracking traditional players fill the town’s many excellent pubs - Kennedy’s, Foley’s, the Snug, Mchugh’s and Hardagan’s - with the headliners: Wallace Bird, Lau, accordion queen Sharon Shannon, Joan Armatrading. But one name stood out on the marquee, that of Van Morrison, coming to Sligo with the promise of a very different kind of show – “Lyrics and Poetry: Emphasis on Words”, with readings of his own work and that of Yeats.

“Last night’s tenor was superb, wasn’t he? Such Italianate passion at the top of his range…” In the pub, the streets and – in this case – over the cereal and croissants of a hotel breakfast, there’s only one topic of conversation in Wexford for 10 days every autumn: opera. During festival time this tiny Irish town on the river Slaney undergoes something of a sea-change. Doctors, plumbers and shop-assistants all transform themselves into the festival staff, ushering audiences, erecting staging and assisting artists.

Finding the mythic echoes of the ancient Greeks in stories about the modern world is not just confined to past greats such as TS Eliot, but is also used by contemporary adapters of old tragedies. Yet Colin Teevan’s new play, which shadows the lives of Irish navvies working in England with echoes from Greek tragedy, goes one better. Asked by the director Lucy Pitman Wallace to rewrite the Oedipus myth through the lens of Krapp’s Last Tape, the playwright has come up with The Kingdom.

Samuel Beckett recalled sinking into a "whirl of depression" while writing All That Fall. Audiences at this production - those, that is, who have managed to score a ticket for this short, sold-out run - are unlikely to emerge into Jermyn Street in a similarly gloomy frame of mind.

The first anniversary of Amy Winehouse’s death seems like both a temptation and an opportunity for a sensationalist, hyperbolic tribute. Refreshingly, this Arena film, which told the story of the night that a superstar in the making performed to an 85-capacity church in the Irish fishing village of Dingle, for the most part avoided the clichés: the word “tragedy” wasn’t even mentioned until 38 minutes in.

The fact that the latest in a long line of Dara O Briain DVDs is already on sale on Amazon is pretty impressive considering that he hasn’t recorded it yet. I know this because the second show of his four-night run at the Playhouse happened to be the one immediately before the gig being filmed for a timely pre-Christmas release. If it captures the warmth and verve of last night’s show it might even turn out to be one of those rare comedy DVDs worth buying.
