Gustavo Dudamel and the Simón Bolívar Symphony Orchestra of Venezuela took the Barbican by storm last night with a thrilling account of Mahler’s Third Symphony, his great exploration of the cosmic order, ascending from raw paganism to sublime transcendence. It's technically the longest symphony ever composed, and here it swept the audience through an epic journey that tilted between passages of gossamer-like intimacy and outbursts of apocalyptic rage.

The Queen’s Hall isn’t going to know what has hit it after the opening weekend of this year’s Edinburgh International Festival. What’s usually the festival’s demure home of chamber music – string quartets, piano trios and so on – was still recovering from Jakub Józef Orliński’s theatrics from Saturday morning, when it encountered this scorching performance of choral music from the Schola Cantorum de Venezuela (★★★★★).

Alejandra Ghersi – Arca – is one of the most influential musicians on the planet in the last decade. Even aside from working with huge names like Björk and Kanye West, her ultra-detailed, high drama, electronic abstractions have set the pace for a legion of artists from very underground to ultra-pop.

As the Statue of Liberty appears in Charlie Chaplin’s The Immigrant, our improvising pianist proclaims “The Star-Spangled Banner”, only for it to slide dangerously.

A young film director writes a script based on his father’s life story and invites his dad to play the part. It’s an interesting gambit, given that the son, Jorge Thielen Armand left Venezuela with his mother at the age of 15 and has not returned since. His father stayed behind, so their relationship has stalled. Can it be reignited?

For as long as I can remember, there has been a continuous loop of original music playing in my mind. My father used to joke about my “tuyuyo” – a little bump I have on the back of my head – that it was my personal repository for music. My husband, less versed in Venezuelan colloquialisms, simply refers to it as “the iPod”.

Insistence was the name of the LA Phil's first game in its short but ambitious three-day Barbican residency - insistence honed to a perfect sheen and focus, but wearing, for this listener at least, some way in to the Shostakovich Fifth Symphony played in the second half.

Former Royal Philharmonic Orchestra principal conductor Charles Dutoit has been exposed, to little surprise from musicians, as something of a roué whose apparent refusal to take "no" for an answer has rubbed up against the new #MeToo world. So his place in last night's concert was taken by Venezuelan Rafael Payare, not yet 40.

The eel is dying. Its body flits through a series of complicated knots which become increasingly grotesque torques. Immersed in a pool of brine — concentrated salt water five times denser than seawater — it is succumbing to toxic shock. As biomatter on the sea floor of the Gulf of Mexico decomposes, brine and methane are produced, and where these saline pockets collect, nothing grows. Dead creatures drop into it; live creatures that linger in it die.

Gone, it seems, is the era of epic three-part Proms. Sunday afternoon's programme, partly billed as a children's hour, might have pleased pianist and pundit Stephen Hough, whose recent broadsheet plea for shorter concerts somewhat overdid the need (lunchtime events already cater to concertgoers in a hurry very well, and the Proms has its late-nighters too). But it left many of us wanting more, not just of Ravel in the second half but also of the distinctive Simón Bolívar earthiness, which was given free rein only in one spirited encore.
