If a standard-sized recital hall can be a lonely place for a solo violinist, playing an auditorium of Barbican dimensions must feel like crossing a desert under pitiless spotlight sun. Happily, Nicola Benedetti’s prowess as a communicator means that she made those trackless wastes shrink into a shared garden where she, and we, explored her instrument’s many kinds of bloom. Defiantly, a solitary figure in red on the enormous stage, she began her recital with Bach’s D minor partita – and the mighty, earth-moving Chaconne which completes it.

Mark Cousins, the multi-award winning director of this strange film, is lying in bed watching Ray Charles speaking on the Dick Cavett Show in 1972. The singer went blind in childhood; how would he respond if offered the chance to see again? “I might turn it down,” says Charles.

Submarines have delivered some memorable on-screen performances, from Run Silent, Run Deep to The Hunt for Red October. On the other hand, we must not overlook the treasurably idiotic BBC series The Deep, which featured a submarine with a “moon pool” in it (this was a big vent permanently open to the ocean). Handy for reaching the sea-bed in a hurry perhaps, but not helpful for getting back up again.

It’s often the company one keeps that makes a journey worthwhile, not the destination. That’s as true for the five ebullient Fort William schoolgirls making their first trip to Edinburgh in Our Ladies as it is for the film’s audience. These Highland hoydens are so much fun, it’s a pity when our brief time with them ends.

The popcorn on offer as you enter the Pleasance’s performing space at the Edinburgh International Conference Centre quickly fills the air with its rich, sugary scent. It’s a smell that sets the scene nicely for a show set in a cinema, but also an aroma that takes on increasingly heavy, cloying, sickly – and inescapable – connotations as Screen 9 progresses.

Ageing Mick wakes up on Portobello beach with two gold rings in his pocket, and embarks on the bender to end all benders in order to work out what or who they’re for. Young Gilly has a poorly pug named Mr Immanuel Kant, but can’t face having it put down. Gaynor has suffered from fibromyalgia for decades, but must put it aside if she’s to see her newborn granddaughter. Dougie and Ciara are preparing for their life-changing arrival with one last hedonistic night on the dance floor.

Fear of Roses Assembly Roxy ★★★

There’s always a tricky balance to be struck with site-specific theatre. What’s more important: the show itself, or its unusual setting? And to what extent does its location enrich or even impact on the essence of the text?

Tunnels Army @ The Fringe ★★★

Displacement looms large over every quietly impressive frame of Limbo, writer-director Ben Sharrock's magnetic film about a young Syrian man called Omar (Amir El-Masry) who finds himself biding his time in the remotest reaches of Scotland on the way to some unknown new life.
