It was a hefty evening, as it needn't necessarily have been throughout, since Shostakovich’s Ninth Symphony can conceal more darkness between the lines in a lighter take. In his second full concert of his second season as the wildly successful and popular Chief Conductor of the London Symphony Orchestra, Antonio Pappano spared us none of the hard-hitting.

The trunk in the title is a luxury item, worth 50 million won – just north of £27,000 – shown sinking in deep water in the opening credits. It weaves through one of the classiest recent collaborations between Netflix and Korean TV, a haunting psychological drama that’s balm to the soul after the mob-handed violence on offer here at home. 

A traditional Korean house has appeared at Tate Modern. And with its neat brickwork, beautifully carved roof beams and lattice work screens, this charming dwelling looks decidedly out of place, and somewhat ghostly. Go closer and you realise that, improbably, the full-sized building is made of paper. It’s the work of South Korean artist Do Ho Suh (main picture).

When the world’s darkness is too much, there is a Netflix rabbit-hole you can disappear down to a kinder place: the Korean romcoms section. This is a recommendation for romcom fans, a warm indulgent bubble bath of a watch. It's like turning the clock back to more innocent times, while full of contemporary pizzazz. 

“I lead a peaceful, idle life, running a bookstore in Gangneung. Honestly, no customers.” Chu Si-eon (Kwon Hae-hyo) is genial and self-deprecating but he was previously a well-known actor and director before he criticised the authorities and was forced to lay low.

South Korean quintet TXT's latest mini-album delivers six meticulously crafted tracks that showcase the group's evolving artistry through everything from dreamy pop to reggaeton to classic R&B.

With its stripped back arrangement – some ethereal guitar chords here, an unforgettably chirpy three-note descending synth riff there, plus vocal lines that flow and blend mellifluously – album opener “Heaven” delivers the mini-album's first and perhaps most memorable earworm.

“The ocean is our home… Even in my next life I will dive again,” says Geum Ok, one of a band of female divers from Jeju, a volcanic island 60 miles south of the Korean peninsular.

The Edinburgh International Festival’s focus on Korea moves to the Queen’s Hall in the festival’s middle week, with performances from two Korean soloists playing alone.

There’s a Korean strain to the Edinburgh International Festival’s programme this year, more in the drama programme than in the music one, but it came to the Usher Hall in Friday night’s concert from the KBS Symphony Orchestra (★★★★). They play a similar role in Korea to what the BBC Orchestras do in the UK (KBS stands for Korean Broadcasting System) and if this concert is anything to go by then they’re a jolly impressive bunch of musicians.

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.
