For Delius – then a young man, visiting Norway in the late 1880s to walk in its mountains – his first encounter with Nietzsche’s Thus Spake Zarathustra was nothing less than an epiphany. Already high on the grandeur of nature in a country defined by its shimmering fjords and austere mountains, he found the text to be an intoxicating affirmation of the glories of the world in a humanistic universe.

There’s a Proms paradox that’s familiar to Early Music fans. Some works are too challenging – too big, too expensive, too uncommercial, too obscure – to do anywhere else. The trouble is, the Royal Albert Hall is the absolute last place you’d want to hear them.

You can't explain stage presence like Anoushka Shankar’s. It just "is". When she steps out in front of a completely packed Royal Albert Hall, and utters a welcoming, exploratory, London-ish “Hi... welcome to my Prom… Oh, my God!”, a friendly connection with audience is made. Instantly and with disarming ease.

Water surged through this Prom from first spray to last drop. But there was nothing damp or diluted about Edward Gardner’s helmsmanship as he steered the London Philharmonic Orchestra through a succession of liquid rhapsodies: three from the early 20th century; one from 1993.

“Some are born to sweet delight, some are born to endless night,” quoth Blake. Beethoven and Bartók knew both extremes, but Iván Fischer and the Budapest Festival Orchestra led us from the most dancing of Seventh Symphonies to the endless night of Duke Bluebeard’s Castle, from explosive A major to quietest C sharp minor. If not everything along the way was perfect, or even in one major case present, the outlines were bold and engaging.

Arvo Pärt was into his 40s before he made had his Big Musical Idea: simplicity. He has spent the subsequent half-century pursuing this ideal, largely through the religious choral music that has been dubbed Holy Minimalism. And in this year of his 90^th birthday, the Proms gave the Estonian Philharmonic Chamber Choir a late-night concert to celebrate this music – and the people turned out, in what was the best-attended late-nighter I can remember.

According to the programme, Lutosławski’s Concerto for Orchestra is heard somewhere around the world every other week. In which case I’ve been unlucky in never having heard it live before, despite being a fan for nearly 30 years. So I was relieved that last night’s Prom’s outing – in Tadaaki Otaka’s farewell with the BBC National Orchestra of Wales, after a 40 year collaboration – didn’t disappoint.

This Prom began in sombre and melancholic shades of grey. Then, as her encore, the superb Georgian pianist Mariam Batsashvili launched into Liszt’s Paganini étude, “La Campanella”, and bells of long-awaited joy rang around the Royal Albert Hall. Under those leaping acrobatic fingers, musical sunshine drove away the clouds.

It started like Sunday afternoon band concert on a seaside promenade, a massive ensemble playing it light. But while there were several too many Shostakovich pops, the Ravel concerto and Walton symphony ahead sailed for deeper waters, And the Bournemouth Symphony Orchestra is on top form, lucky to have one of the world’s best conductors, Mark Wigglesworth, in charge. 

The auditorium and arena were packed – and the stage even more so, bursting at the seams with players and singers: the perfect set-up for a First Night of the Proms. This is traditionally an opportunity to programme a large-scale choral work, and last night that was Vaughan Williams’s seldom heard Sancta Civitas.
