Visit Ainola, Sibelius’s woodland house by Lake Tuusula north of Helsinki, and you’ll be told the story of the green stove. It appears that the famously synaesthetic Finnish composer identified the shade of his heating installation with the key of F major.

With the London Symphony Orchestra often playing like some commanding and relentless force of nature, Sir Simon Rattle steered two mighty avalanches of Nordic sound into a concert of granitic authority last night. However, I suspect that many people will have left a packed Barbican thinking most of the uncanny winter wonderland that separated these two mountainous symphonies.

There must be something of a beauty parade going on in Liverpool now that Vasily Petrenko has called time on his tenure at Philharmonic Hall.  After all, someone will need to step into his shoes from 2021 after he departs for the Royal Philharmonic Orchestra. It was refreshing, therefore, to welcome Anu Tali to conduct the Royal Liverpool Philharmonic, making her debut with the orchestra.

The LSO and Sir Simon Rattle have been launching their new season with a mini-festival, if not so-called, mixing and matching some delectable repertoire. This was their third concert in four days – and its programme was wonderfully shaped, bringing together three works written within 11 years of each other, each from a composer with a unique voice that spoke for his whole nation in one way or another.

Music-lovers who normally balk at the sight of national colours in a concert hall would surely have forgiven the little Estonian flags – in stripes of blue, black and white – that waved happily at the conclusion of this Prom.

Let's be honest, this is the least interesting Proms season on paper for years, at least in terms of adventurous repertoire choices, following on the heels of the best in 2017. Yet in statistical terms it's more comprehensive and multi-media-friendly than ever, starting tonight with a free "Curtain Raiser" performance before the official First Night tomorrow - see David Kettle's choice below – and ending some 75 main Proms and 11 smaller-scale beauties later on 8 September.

It’s as intricate as it is concise. The depth to the architecture of James MacMillan’s Saxophone Concerto – which was given its world premiere this week by saxophonist Amy Dickson and the Scottish Chamber Orchestra – is quite astounding, and all the more so for being packed into three five-minute movements.
