Make Arvo Pärt the bulwark of any concert and you can surprise as well as delight the full house he’s likely to win you with the rest of your chosen programme. This was a beautifully planned showcase for the Estonian Philharmonic Chamber Choir under its Latvian conductor Kaspars Putniņš, poised between the introspective and the extrovert both within the all-Pärt first half and what followed after the interval, where Estonian composers no less precious than Pärt to their compatriots framed the late Jonathan Harvey’s mesmerising seraphics.

Jörg Widmann writes fast. He is also one of the few young German composers who can write distinctive and idiomatic music without feeling the weight of his country’s musical heritage on his shoulders at every turn. Surprisingly, then, his Clarinet Quintet, which here received its UK premiere at Wigmore Hall, was eight years in the making, and was initially abandoned because "music history ... suddenly appeared as a great burden".

Oliver Knussen and the Royal Academy of Music Symphony Orchestra here took us on a whistle-stop tour of Stravinsky, early and late. Few composers changed so in style so dramatically over the course of their career, so there was plenty of variety here. And just for good measure, a work by Stravinsky’s teacher Rimsky-Korsakov was included too, his Russian Easter Festival Overture. Both composers were excellent orchestrators, and Knussen’s programme proved ideal for showcasing the players’ talents.

You could probably guess from the assembling audience that the orchestra making its Barbican debut last night came from Milan. That many mink coats rarely congregate in a London concert hall.

You can’t help liking Joshua Bell. The Peter Pan violin soloist of the classical world has been in the business for more than 30 years and still has his boyish looks and, more importantly, his enthusiasm and sense of enjoyment in making music. At the Bridgewater Hall last night the pages of his score stuck together at one point between movements, but he had a quip for the audience and carried on with a smile.

Rapture, ecstasy, ardour, and a few cheeky fumbles in the bushes – Louise Alder and James Baillieu’s Wigmore recital promised “Chants d’amour” and delivered amply, giving us love in all its bewildering, technicolour variety.

Colin Currie is increasingly coming to be seen as Steve Reich’s representative on Earth. His Colin Currie Group was founded in 2006 for a Proms performance of Reich’s Drumming and has gone from strength to strength, now touring the world with Reich’s music.

This was an evening of Iberian highways re-travelled, but with a difference. At the beginning of 2016, the centenary of Spanish master Enrique Granados's untimely death, two young pianists at the National Gallery shared the two piano suites that make up the original Goyescas; finally last night at the Barbican we got the opera partly modelled on their deepest movements.

Alisa Weilerstein is making two visits to Manchester in just over three weeks. Last night it was with the Hallé, next time she’ll be guesting with the Czech Philharmonic. This one was to play the solo in Shostakovich’s First Cello Concerto, with Sir Mark Elder conducting.

Living-museum recitals on a variety of historic instruments pose logistical problems. Telling The Arts Desk about his award-nominated CD of mostly 19th-century works for horns and pianos, Alec Frank-Gemmill remarked on the near-impossibility of reproducing the experiment in the concert-hall: playing on four period horns would need several intervals, and colleague Alasdair Beatson would hardly be likely to have the four pianos in the same room.
