Landscape painting may be dominated by the Dutch. But in music it is the Austrians who know best how to evoke the majesty of the great outdoors. In the first of last night's two Proms, one of the most awesome of Anton Bruckner's snow-capped symphonies, number five in B flat major, accompanied a new high climb through the Tyrol from fellow Austrian Thomas Larcher for two great musical off-pisters: violinist Viktoria Mullova and cellist Matthew Barley.

This year’s Choral Sundays at the Proms are a wonderfully mixed bag. Mighty choral touchstones are represented by Mendelssohn’s Elijah, both the Verdi and Mozart Requiems and Beethoven Missa solemnis, but there’s also an enticing strand of curiosities. Looming largest among these has of course been Brian’s Gothic Symphony, but emerging now from its sprawling shadow are less obscure but no less interesting works – Britten’s Spring Symphony, and last night Mahler’s folkloric Opus 1 cantata Das klagende lied.

They came in their thousands again last night, most – I’m guessing – for “the Elgar”. Lacking faith that Tasmin Little could fill the enormous soul of that most elusive of violin concertos – a prejudice, alas, fulfilled - I put my money on the polytonal jungle Percy Grainger grows from pastoral seeds at the heart of his wacky In a Nutshell Suite. Yet unforgettably though Sir Andrew Davis swept it along, even Grainger was overshadowed by the lone, late-night transcendentalism of folk singer June Tabor.

Nine out of 10 attempts to feed an audience's visual responses to abstract music are doomed to failure; a great communicator will always conjure stronger pictures in the listener's mind. And there's no doubt that young violinist Alina Ibragimova communicates at the highest level. But here she simply held her own to work in shadowplay with both the mysterious spaces of London's most atmospheric venue and the even more intangible visions of twins Timothy and Stephan Quay. Their film around Bartók's Solo Violin Sonata, though defying intellectual analysis and easy correspondence with the musical ideas, is pure choreographic poetry.

In case anybody had the bizarre notion that the Classical Brits was getting a trifle too classical, the 2011 version of the event was rebranded as the Classic Brit Awards. That would seem to open the door to almost anything - classic rock perhaps, or classic schmaltz (well, waltzmeister Andre Rieu did win Album of the Year). The night climaxed with Dame Shirley Bassey singing "Goldfinger", capping a tribute to the late John Barry, and sounding nowhere near as "classic" as she used to.

Its advertised centre of gravity, a concerto specially commissioned from affable whiz-kid Nico Muhly, turned out weightless, and not in a good way. Yet the programming of the Aurora Orchestra's latest adventure showed us why the Arts Council were right to fund this young and dynamic constellation. OK, so I'd have been happiest with a whole evening of Hindemith Kammermusik rather than one movement. But for the new generation of pick-and-mix onliners, the seven eclectic works on the bill couldn't have been more enticing, thanks to the iron fist of velvet-glove live stream presenter-conductor Nicholas Collon.

This week we’ve offbeat violin and viola duets played by a renowned husband-and-wife duo, Scarlatti keyboard sonatas played on piano, and a very Italian take on Shakespeare from one of the 20th century’s fieriest conductors.

Two hundred years ago society ladies snipped theirs and gave it the poet Byron. Indigent women cropped theirs and sold it for wigs. But never in the history of human hair has a woman put her tresses to such a unique use. A woman, unnamed, has donated her hair to the violinist David Garrett, and he has used it to string his bow.

Yehudi Menuhin's influence continues to reach out a hand to young instrumentalists. His Menuhin Violin Competition for young players under 22 is internationally known; last weekend in the Waterloo Chamber of Windsor Castle - a staggeringly picturesque setting - some exceptional violinists, violists and cellists sought the laurels at the Windsor Festival International String Competition, Britain's major professional prize for string players set up in Menuhin's honour three years ago.

It's rare for demanding though not, I think, unduly cynical orchestral musicians to wax unanimously lyrical about a new conducting kid on the block. But that's what happened at the 2009 Besançon International Conducting Competition when BBC Symphony players in residence placed their bets on the obvious winner, 30-year-old Kazuki Yamada. He repaid their good faith last night in a real stunner of a London debut programme featuring two very different challenges to his long-phrasing vision and the most dramatic new violin concerto I've heard in the last two decades.
