Writing for two pianos is something that – until last year – I had not attempted. I was contacted by Katya Apekisheva and Charles Owen, two pianists who have performed as a duo for many years, asking me to compose a duet for them to perform at the inaugural London Piano Festival. I met Charles back in 2014 when he performed my pieces A Hudson Cycle and Fast Stuff in New York. Time constraints led me to restructure and rewrite an existing piece in my portfolio, Fast Cycles, which I wrote for the late John Scott.

The B Minor Mass comes in many shapes and sizes. Martin Feinstein opts for a bright and bijou approach, with period instruments, one to a part, and a choir of ten. The small ensemble sometimes lacks finesse, but makes up for it in dynamism, passion, and sheer joy. There was nothing chamber-scaled about this reading: it was all big gestures and direct emotions.

Described by Courtney Pine as "the most exciting jazz band to come out of the UK" and hailed in the press as the new young lions, Empirical broke cover in 2007, topping album of the year charts with their self-titled debut and picking up wins at the prestigious EBU/European Jazz Competition and the Peter Whittingham Jazz Award all within a few months.

It is not surprising that Piano Circus rarely play on six real pianos (although the photo on last night’s programme cover shows just that). The expense, the stage space required and the logistical complexity all militate against it. But the sound produced by six highly amplified digital keyboards is so far removed from that of six pianos as to be another thing entirely, and the overriding memory of this concert is an unpleasant, and unpleasantly loud, piano-ish blast of sound beating me about the ears.

The music of Olivier Messiaen lends itself ideally to the kind of multimedia project created by Cordelia Williams. His titles tell stories of terror and redemption, Man, men, God and angels. His chords burst with colour, not only the green and gold of Christmas or the red and purple of Crucifixion but the pulsing of a slow journey, stripes of redemption, layers of wakefulness. The only drawback is that the composer himself was very sure about what those stories and colours were, leaving little room for later interpreters to add their own perspectives.

This was one of the most crazily ambitious music projects of the year so far. Co-curators Sam Mills and Susheela Raman, with generous sponsorship, assembled their favourite musicians in different styles from Greece, Lebanon, Ethiopia and Russia under the title of Sacred Imaginations: New and Ancient Music From the Near East. What could have been a spiritual dog’s breakfast was, even if the sense was the wheels might come off at any moment, a thrilling musical journey and a triumph.

Zeitoper, single scene micro-opera for modern times, enjoyed a brief vogue in the Weimar era, but disappeared as fast the Republic itself. This programme from the Continuum Ensemble resurrected four examples, all from the years 1927-28, to offer a snapshot of Germany’s quickly evolving music theatre scene between the wars. The works, by Hindemith, Ernst Toch and Kurt Weill, are short, with little narrative, and even less musical subtlety.

The fifth Songlines Encounters Festival at Kings Place brought together artists from around the world, offerering a powerful cultural kick-back against all manner of extremist positions. The opening Thursday featured young Portuguese Fado singer Gisela João, with Cypriot trio Monsieur Doumani, and the closing Saturday paired the Shikor Bangladesh All Stars with the Anglo-Bangladeshi Afrobeat Latin grooves of Lokkhi Terra.

Opening It’s All About Piano!, a short but packed festival shared between Kings Place and the Institut français in Kensington, Mikhail Rudy made a rare appearance in the UK. The premise was unusual if hardly revolutionary, a meeting of music and film in which it was not obvious which was the accompanying medium. Was Rudy the silent-film pianist, or were the movies illustrative of latent narratives in Janáček and Musorgsky? Neither. And therein lay the recital’s success.

Mari Kvien Brunvoll - Norwegian improviser, singer and composer - enters the Kings Place stage more like a pianist's page-turner than the night's sole performer, and sits cross-legged at her pedals. Dressed in a neutral dark grey, she doesn't seek applause so instead we are left silently watching her adjust a microphone and untie a little red book. Her methodical calm creates a patient audience, intrigued enough to find her subtle actions compelling.
