There’s always been something of a buzz in the air at East Lothian’s Lammermuir Festival. It’s the feeling that it’s somehow a special privilege to discover its performances – whether they’re from international names or emerging artists, challenging, provocative and illuminating by turns – across the region’s exquisite and little-known churchs, halls, theatres and other venues.

In a small town on the Polish-Czech border where the mobile signal wanders between countries’ operators and only three inhabitants stick it out through the winter, animals are wreaking a terrible revenge. The bodies of murdered men, united in their penchant for hunting, have turned up in the forest, violently dead and rotting. Deer prints surround one corpse, beetles swarm another’s face and torso. Foxes escaped from an illegal fur farm need little motive to exact summary justice on their former jailor.

“When you were our age, how did you imagine your life? What did you hope for?” It is a video of a classroom south-east of the Périphérique separating Paris from the working-class suburbs. The students are mostly girls between fifteen and sixteen and they wear make-up, jewellery, low-cut tops – we understand they’re sexy, confident, cool. Several are African, North African, Caribbean.

There's surprising and then there's The Lehman Trilogy, the National Theatre premiere in which a long-established director surprises his audience and, in the process, surpasses himself. The talent in question is Sam Mendes, who a quarter-century or more into his career has never delivered up the kind of sustained, smart, ceaselessly inventive minimalism on view here.

So the ambient revival continues apace, getting deeper and wider with each passing year. From the interstices between the classical concert hall, abstract art installations, the backroom of more insalubrious little raves and festivals, the small hours on oddball online radio stations, and the spaces into which people get lost as they defocus and absorb themselves into their headphone soundtracks on commutes seems to seep more and more sound that is textural above all.

The world was captivated by the Arab Spring – thousands of citizens rising up in unity against longstanding dictatorships, filling squares and refusing to bow. But for many of us, it was a world away; the crowds were a single organism, thinking and acting as one. What The Nile Hilton Incident does incredibly well is create the feeling of being an individual on those streets: placing you in that simmering cauldron, a city on the edge.

Adam Gorb’s The Path to Heaven, with libretto by Ben Kaye, is his longest work to date (almost two hours’ running time without interval) and on a story that could hardly be more tragic – the Holocaust. Its premiere at the Royal Northern College of Music was conducted by Mark Heron and given by members of Psappha with singers and musicians from the RNCM, directed by Stefan Janski.

Hot in the burning footsteps of Bargou 08, last year’s subtle but daring mix of traditional Tunisian sounds and electronic beats and textures, Sofyann Ben Youssef launches a new project under the name of AMMAR 808, Maghreb United.

One space, one person, one story, one voice – the monologue is theatre distilled, the purest form of entertainment.
