At the beginning of last night's show, Herbie Hancock looked like he was going to perform with the dignity and serenity befitting a 72-year-old with some 50 years playing experience. The improvisation that launched from a base of Wayne Shorter's “Footprints” was elegant, charming, tasteful and often very beautiful. The synthetic instrumental loops that he triggered via a couple of iPads mounted on his grand piano as backing were unobtrusive to begin with and had a delightfully loose groove.

Britain has a grudging relationship with country music – we’ve never produced a successful country singer (although the likes of guitarist Albert Lee and several songwriters have prospered in Nashville) and our love for the likes of Johnny Cash is tempered by a contempt for much of what is marketed as country music. I’m often surprised by how  blues, soul and jazz lovers can admit ignorance of a musical form so closely related to other American genres.

Benjamin Grosvenor made his Southbank recital debut last night in a sold-out Queen Elizabeth Hall in another milestone in his unstoppable evolution from wunderkind to fully-fledged concert star. It has been a good year for the 20-year-old pianist, during which he added a Classic Brit and two Gramophone awards to a Critics’ Circle accolade, Decca recording contract and tenure on the Radio 3 New Generation Artists scheme.

Some symphonies are natural curtain-raisers: Sibelius’ Third is one. Music began with rhythm and in this piece the cellos are the distant drummers who bring us back to basics with their curt opening measures. Osmo Vänskä clipped the rhythms are kept them on a tight rein - because he knows how this piece goes, how Sibelius’ search for new found economy and textural leanness lends the music an uneasy tension.

Forty years ago Michael Nesmith was the tall, woolly-hatted Monkee people called “the talented one”. Faint praise maybe, but there was nothing mediocre about the country rock albums he went on to make. Nesmith had another advantage. His mother had invented Liquid Paper giving him the financial freedom to experiment as he pleased. He soon became a true renaissance man. But according to one newspaper, by 2011 he was also increasingly reclusive and eccentric. Even the promoters billed last night’s concert as “rare and exclusive".

When The Unthanks staggered into the spotlight with their haunting and beguiling Mercury Award-nominated 2007 album The Bairns, with bracing songs about infant mortality and child abuse, they became a folk band adored by people who don’t even like folk. They were spiritual sisters to brilliant mavericks like Antony & the Johnsons or Robert Wyatt (they did an album of covers of both artists' songs) while remaining firmly rooted in their native Northumberland.

Stanislaw Skrowaczewski. That's quite a mouthful. Bruckner's symphonies can be too. But this is one of the reasons why Skrowaczewski has acquired quite a cult following for his Bruckner performances; it's why I once drove all the way to Zurich to hear him conduct one. His Bruckner is never offered as an indigestible slab of meat. It's never hard or chewy.

The quest for the spiritual in the musical has been the dominant preoccupation of Jonathan Harvey’s since his earliest works. Rudolf Steiner’s philosophy has been an acknowledged influence on the composer, who has made a career of exploring what Steiner described as “the special character of the individual note”, which “expands into a melody and harmony leading straight into the world of the spirit”.

Can two half-orchestras playing together ever be better than one well-established organism? The second and third concerts in yet another special project masterminded by Vladimir Jurowski, drawing together British and Russian perspectives on war and peace, proved that they could. It may have been disappointing to find the Russian National Orchestra on Thursday evening launching so cold-bloodedly into the feral start of Vaughan Williams’s Sixth Symphony.

What, another review of an LPO/Jurowski concert in less than a week? Reasoning the need, it only has to be said that other orchestras may kick off their seasons by mixing the unfamiliar with core repertoire, but none would dare launch with not one but two programmes featuring this only-connect kind of singularity (and more to come in the “War and Peace” series next week).
