Stockhausen stands alongside Monteverdi and Beethoven as a composer who exploded the understanding of his art. Stockhausen deeply changed the relationship between space, time and music; there’s a human, intimate dimension to his composition, and he predicted the future.

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.

The last time Sergio Mendes, the Brazilian bossa nova legend, played at the Royal Festival Hall was in 1980 when he opened for Frank Sinatra. He shakes his head in wonder at the memory, though it’s not so long ago in the scheme of things – his career started in the late 1950s.

Vladimir Jurowski is always a conductor for making connections, so one wonders why Brahms's Second Piano Concerto wasn't the first-half choice in this programme from the start (the advertised original had been the much stormier No 1).

Expect no cliches about toreador pianism. Red-earth flamboyance is not Javier Perianes' style, and the seven dances he offered in his programme - eight including an encore - by fellow Spaniard Manuel de Falla were not the most consistently engaging part of the recital.

Great conductors, like efficient auto engines, apply a lot of torque – they can use a little energy to achieve great surges of movement. Now aged 91, the American-born Swedish maestro Herbert Blomstedt sometimes hardly seems to raise his baton-free hands. His feet, meanwhile, remain more or less immobile. Yet, like some highly-geared sports car, last night the Philharmonia zoomed, boomed or swerved at the merest distant kiss of his fingertips.

If Gilbert and Sullivan did the Bible it would sound a lot like Hubert Parry’s Judith. Premiered in 1888 and last heard in London a year later, the oratorio – whose principal claim to fame is as the original home of tearjerker hymn tune Repton, better known as “Dear Lord and Father of Mankind – has been lovingly restored to life by conductor William Vann and the English Song Festival, who will record it with Chandos later this year.

Mozart in E flat (the Overture to The Marriage of Figaro) and in G (the K.453 Piano Concerto), and Schubert in C – the “Great” C major Symphony, no less – ushered spring into the Festival Hall on a warm and sunny Sunday afternoon.

No successor has yet been named to Vladimir Jurowski as Principal Conductor of the London Philharmonic, so it is interesting to note that Edward Gardner is making several appearances with the orchestra this season. The two conductors are similar in their dynamic approach and brisk, efficient tempos.

Standing next to the warm brown beast of a piano built by Blüthner in Leipzig in 1867, Sir András Schiff advised his audience last night to clear their minds and ears of preconceptions. He told us that his rendering of Brahms’s first piano concerto – tonight, he will return to play the second – “should be like a first performance”. In reality, he added, that premiere (in 1859) turned out to be “a colossal failure”.
