Prokofiev Flute Sonata in D, Op. 94 | Pahud

Prokofiev wrote the Flute Sonata in 1943, in wartime evacuation, in the middle of War and Peace. He said he wanted something “with classical, clear, transparent sonority” — and what came out is a sonata in D major that behaves as if the previous thirty years had not happened. No irony, no grimacing. Sviatoslav Richter and the flautist Nikolai Kharkovsky premiered it in Moscow on 7 December 1943. The following year David Oistrakh talked him into rewriting it for violin, which became the Second Violin Sonata, Op. 94bis, and that version is now played roughly ten times as often. Flautists have a legitimate grievance here. The piece is native to the flute — the long, wide-interval melody in the first movement, the way the third movement sits in the instrument’s weakest register and asks it to sing there anyway. On the violin all of that is merely beautiful. On the flute it is beautiful and slightly precarious, which is better. ...

Bernstein Candide Overture | Bernstein, London, 1989

Leonard Bernstein was born on today (August 25) in 1918. Candide opened on Broadway in 1956 and closed after two months — a famous, thorough failure that Bernstein and his collaborators kept revising for the next thirty years without ever quite fixing. The overture survived on its own. It is four and a half minutes long, it gets played by more orchestras than almost any other American concert piece, and it is a small masterclass in how to be funny in orchestral writing without ever winking at the audience. ...

Vivaldi Flute Concerto in G minor, RV 439 | La notte

Vivaldi’s Op. 10, published in Amsterdam around 1729, was the first set of concertos for transverse flute ever printed. Before that the instrument was a curiosity in the orchestra; after that it had a repertoire. Six concertos, and the second one is La notte — the night. It is a strange piece, structurally. Instead of the usual fast–slow–fast, it runs through a sequence of short movements with titles: a Largo opening, then Fantasmi — ghosts — then a second Largo, a Presto, then Il sonno, sleep, and finally an Allegro. ...

Tchaikovsky Valse-Scherzo, Op. 34 | Perlman

Tchaikovsky wrote the Valse-Scherzo in early 1877, a few months before the Violin Concerto, and it is his second and slighter work for violin and orchestra — six minutes, C major, no ambitions beyond charm. The printed score carries the inscription à Monsieur Joseph Kotek: Iosif Kotek, his former pupil at the Moscow Conservatory, the violinist who would sit beside him the following summer working through the concerto bar by bar, and the man Tchaikovsky wrote about in letters to his brother in language he used for nobody else. ...

Debussy Fantaisie for Piano and Orchestra, L.73 | Lento

Claude Debussy was born on today (August 22) in 1862! Happy birthday to the master! The Fantaisie for Piano and Orchestra (L.73) was composed in 1889–90 and never performed in Debussy’s lifetime. When a Paris concert was arranged and he learned that only the first movement would be played, he pulled the parts from the stands before the rehearsal began. He would rather the piece not be heard than heard incompletely. It wasn’t premiered until 1919, a year after his death. ...

Grocery Inflation by The Economists

The Economists has an podcast episode discussing grocery price inflation (up 25–30% globally since 2020). Who’s to blame for rising food prices? Money Talks | Business https://www.economist.com/podcasts/2026/08/20/whos-to-blame-for-rising-food-prices?utm_campaign=shared_article An easy way to understand it, I think, is to trace down step by step on the supply chain. TLDR: cost drives up price. No one seems to be making more money: Consumer facing supermarket chains’ operating margins remain thin (1–4%), markets are highly competitive. Because wholesale costs to grocers went up alongside retail prices, supermarkets are largely passing costs through rather than driving the price hikes. Labor and logistic expenses are higher: labor shortages in food processing, packaging, and long-haul refrigerated trucking have forced companies to raise wages and shipping rates, creating a lot of cost pressure. Farmer’s input costs (fertilizer, energy, seeds, and equipment) spiked due to global events and inflation. And since commodity markets are controlled by a few dominant processors, farmers have been unable to pass along higher costs, shrinking their margins to historical lows (under 15 cents of every food dollar reaches the farmer). Besides, extreme weather events, droughts, and disease outbreaks disrupt key crop and livestock yields. The Vegetable Basket in China The biggest trauma in Chinese history books always reads like “drought, flood, femine, death, empire fall”. There’s a term in Chinese 民以食为天 (food is first priority in people’s life). ...

Mussorgsky Pictures at an Exhibition | Ravel Orchestration

In 1874, Mussorgsky wrote a piano suite in memory of his friend Viktor Hartmann — a painter and architect who had died suddenly at thirty-nine. The suite moves through ten of Hartmann’s works like a walk through a memorial exhibition, connected by a recurring Promenade theme that is Mussorgsky himself, moving from picture to picture. A gnome. A medieval castle. Children quarreling in a Paris market. An oxcart so heavy the wheels barely turn. A witch’s hut. And finally, the great gate of Kiev — massive, monumental, the brass building until the hall shakes. ...

Stravinsky's Firebird | Suite (1919) — yes, another ballet suite-d

Yes, it’s another ballet, and we’re listening to the suite. Deal with it. The Firebird (1910) was Stravinsky’s first commission for Diaghilev’s Ballets Russes — and his breakthrough. He was twenty-seven. The ballet draws on Russian folklore: the Firebird, a magical creature of light, helps Prince Ivan defeat the immortal demon Kashchei by revealing the secret of his deathless soul. Stravinsky’s teacher was Rimsky-Korsakov, and it shows in the brilliant orchestration and Russian folk material woven in with care. But it already goes further than anything Rimsky-Korsakov wrote. The Infernal Dance is violent in a way that points directly toward what came next: Petrushka in 1911, then The Rite of Spring in 1913 — until he finally blew up the concert hall. ...
