A performance of Olivier Messiaen’s kaleidoscopic Turangalîla-Symphonie is always going to be a bit of an event. The Edinburgh International Festival set this one up nicely by making it not only the impressive culmination of a four-concert residency by the London Symphony Orchestra, but also the centrepiece of a group of Messiaen-themed performances.

This concert, the Edinburgh International Festival debut of the Castalian Quartet, almost didn’t happen due to the illness of their second violin, Daniel Roberts. Then, a couple of days ago, in stepped Yume Fujise, leader of the Kleio Quartet, to save the day, which is no mean feat considering that this programme featured both a world premiere and the knottiest of Beethoven’s late quartets.

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.

Chopin’s piano concertos and Strauss “symphonic fantasia” Aus Italien are young men’s music, bursting with inspired ideas, but baggy at times, hard to steer. Elgar’s In the South is up there with the mature Strauss tone poems – even if it couldn’t have taken the shape it did without them – but here the steering itself was the problem: missing the exuberance, the Philharmonia’s Principal Conductor Santtu-Matias Rouvali stretched it on the rack.

The National Youth Choir of Scotland have the most easily pronounceable acronym in Scottish music: everyone up here knows who you’re talking about when you mention NYCOS.

The Budapest Festival Orchestra never stops proving what a great ensemble it is. In last night’s concert, the third Prom of its weekend residency, the miraculous ways in which the absurd humour of Ligeti, the deep soulfulness of Bartók and the implacable genius of Beethoven were brought to the surface were not just joyful and completely fulfilling, but also unfailingly drew in the attention of the whole audience in a completely full Royal Albert Hall.

It would be worth travelling a long way to hear the Budapest Festival Orchestra giving such a lithe, athletic performance under its founder and Music Director Iván Fischer of Glina’s Ruslan and Lyudmila Overture. That was the Radio 3 and Proms Audience Choice from 19 overtures and preludes whittled down to three. What happened next, despite some equally lustrous playing, didn’t always work so well.

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.

“Very traditional, but fun,” ran the verdict of one fellow-traveller as we waited for a bus outside the Royal Albert Hall on Saturday night. No one can gainsay the infectious fun that the Budapest Festival Orchestra bring to every gig. For all its musical accomplishment, Iván Fischer’s all-singing (yes, they did) if not quite all-dancing (yet) outfit never forget that they belong to a, rather elevated, branch of show business.
