Escapees from Eurovision in Westminster on Saturday night might have discovered that a continent-wide enthusiasm for crowd-pleasing international styles arose long before the age of glitzy pop. Two accomplished Spanish groups performed at St John’s Smith Square within this year’s London Festival of Baroque Music. Both came with an attractive, unfamiliar 18th-century repertoire from their homeland. It showed that, across the decades from Handel to Haydn, the hegemonic sounds of Italy could be zestfully customised to suit national tastes.

Il Trionfo del Tempo e del Disinganno is the opposite of a jukebox musical. So fertile, so overflowing was the 22-year-old Handel’s musical imagination, that his very first oratorio, composed during his time in Rome, would become a chest full of music the composer returned to again and again, pilfering and self-plagiarising over the ensuing decades. All those hits from Rodelinda, from Agrippina, Partenope, Rinaldo: he wrote them here first.

Shortly before his death, Rachmaninov proposed recording the two-piano version of his swansong Symphonic Dances with Vladimir Horowitz. A curse on that RCA executive who turned the offer down. What amazes is how much pianistic magic can make up for the orchestral wizardry of the more familiar incarnation. The Kolesnikov-Tsoy duo is the one to redisover it now, and they did the same for Mikhail Pletnev’s recreative genius in music from Prokofiev’s Cinderella.

Who’d have thought Florence Price, Rachmaninov, Gershwin and Brahms would all fit the (unspoken) theme of 1930s America? Brahms made the bill by virtue of Schoenberg’s 1937 arrangement of the C minor Piano Quartet, so outlandish and camp that you’d be tempted to credit Stokowski as the orchestrator. Like Rachmaninov’s Rhapsody on the Theme of Paganini, it needs vertiginous audacity: that came in spades from conductor Joshua Weilerstein and pianist Martin James Bartlett.

Getting on for 27 years ago, Thomas Adès’ These Premises Are Alarmed was one of the pieces commissioned by the Hallé for a premiere in the opening series of concerts at the new Bridgewater Hall, conducted by Kent Nagano.

Paul Lewis secured his reputation as a leading advocate of the Viennese Classical repertoire with two releases of late Schubert sonatas on Harmonia Mundi. That was 20 years ago, but he returned to Schubert in 2022, with a release of earlier sonatas, music that requires more interpretive personality, something that Lewis can always provide.

For its 22nd concert the hugely successful initiative, Through The Noise, took its audience to The Jago in Dalston, the live music venue formerly known as Passing Clouds. Here, on a stage more familiar with reggae, blues and Afrobeat, 25-year-old classical trumpeter Aaron Akugbo joined forces with harpist Milo Harper (pictured below) for a series of sultry, haunting numbers that explored the possibilities of this unusual pairing.

Rigorous, hauntingly original and unlike each other, Britten’s three numbered quartets could share a programme and still stake equal claims on our attention. That might be tough on the players, but the Castalians haven’t been easy on themselves in the three concerts they’ve given to share out the honours between Britten and other composers.

“Let the organ thunder!” is the sentiment a lot of us will associate with an orchestral concert featuring the king of instruments. The Hallé’s programme with Anna Lapwood as soloist (repeating, from her BBC Proms debut with them in 2021, the Saint-Saëns “Organ” Symphony) seemed designed to evoke that thought.

But the organ in the Bridgewater Hall isn’t exactly made for thundering. Big Bertha it is not. What it is really good at is a light, clear and sometimes fiery sound – ideal for Poulenc’s 1939 Organ Concerto, which was the undoubted highlight of the evening.

Brett Dean’s opera Hamlet will play at the Bavarian State Opera in Munich in June: the next stage of an acclaimed progress that began at Glyndebourne in 2017. Now on the last stretch of his three-year stint as composer-in-residence with the London Philharmonic Orchestra, the prolific and versatile Australian – formerly a violist with the Berlin Phil – evidently still has warring royal families on his mind.
