The Prince Regent’s Band was formed in 2013 and, like very many chamber ensembles, was created when a group of us found that we shared a number of interests in common. The musicians that make up the ensemble are all specialist historic brass players and can be regularly heard performing in principal chairs with a number of leading period instrument orchestras. We all shared an enthusiasm for and a curiosity in brass chamber music from the long 19th century.

A certain online scandalmonger and coffin-chaser likes to preface news of deaths in the musical world with "sadness" or "tragedy", usually when neither he nor we have heard of the person in question. But the end of Dmitri Hvorostovsky's two-and-a-half-year struggle with brain cancer really does make opera-lovers very sad indeed – not just because he was only 55, but also because one of the world's most beautiful lyric baritone voices still had much more to give.

What does it take to be included in the Taylor Wessing Photographic Portrait Prize exhibition? This year 2,423 photographers entered 5,717 images: 2,373 of those photographers are left wondering what it takes to make the grade. Remarks from the judges are a little on the Delphic side: "Those we have selected provoked a connection that resonated in all of us."  "It’s always tricky to whittle down to the contenders." "We simply nominated our favourite pictures…".

When I was sent to an adult high security prison aged 14 all the normal colour, shapes and movement that I saw around me each and every day as a child disappeared. It wasn’t there. Prison does that; it’s all straight lines, hard on the eye, hard to the touch. There are square walls or oblongs but there are no triangles, no interesting shapes. It was a harsh environment and I was a child, the softness of that child taking all of that in.

Óttarr Proppé, the stylish chap pictured above, was appointed Iceland’s Minister of Health in January this year. Last Saturday, when the shot was taken, he was on stage in his other role as the singer of HAM, whose invigorating musical blast draws a line between the early Swans and Mudhoney. At that moment, at Reykjavík Art Museum, it was exactly a week on from the declaration of the first results in the country’s Parliamentary election, the second within 12 months.

"Vary the song, O London, change!" sings Tom Rakewell as he tires of the great metropolis. WH Auden and Chester Kallman's libretto for Stravinsky's The Rake's Progress strikes a chord with me too. London has magnificent opera but, at the top end, it comes at a price. Not just for the audience but for the singers. Lavish sets and costumes force historical productions into revivals. Singers fly in, rehearse for a few days, and slot themselves into the existing blueprint.

I was invalided out of the army in 1986. I’d been an army scholar through school and had a bursary at university. I went on to drama school then became an actor, and subsequently a writer and director. But I’ve always been passionately interested in how the military, and the people in it, are portrayed to the wider world.

I was recently in the UK for some solo recitals and to make my debut with the Royal Scottish National Orchestra. One of the highlights of the trip was playing a similar programme in two very different settings: first on some magnificent period instruments and then a week later on a modern Steinway piano at Wigmore Hall. Having never before performed publicly on historical instruments, my recital at the Cobbe Collection at Hatchlands Park in Surrey felt like a complete experiment.

The Viennale is one of the best film festivals in the world and an indispensable part of Vienna’s cultural life. Yet this year’s edition was launched amid trying times.

I remember very well the first time I read Swann’s Way, the first part of Marcel Proust’s monumental masterpiece, In Search of Lost Time (À la recherche du temps perdu). I was struck not only by the depth and beauty of the novel, but also the crucial role that music played in the narrative.
