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.

What a versatile master is the Royal Opera’s resident dynamo Antonio Pappano. On Saturday night, he was in the Covent Garden pit getting big-band sounds and tender elegies from the whole orchestra in Turnage’s Anna Nicole. And here he was again, moving from a surprisingly fine score to a great one, the shadow-of-mortality approach to Chinese poetry that is Mahler’s Das Lied von der Erde, albeit in its ingenious chamber reduction by Schoenberg. Oh, and with the small detail of a mezzo’s ultimate challenge being faced by a baritone.

Earlier this month something happened to me that's never happened before. Brian Ferneyhough's Sixth String Quartet roughed-up my critical faculties and left them for dead. I couldn't tell you what had happened, why, in what order, when. As it finished, small birds circled my head. So I entered Brian Ferneyhough Day yesterday at the Barbican as one would an egg-beater, knees a-knocking.

So the Berlin Phiharmonic’s high-profile five-day residency staked its ultimate curtain-calls on one of the most spiritual adagio-finales in the symphonic repertoire (most of the others, like this one to the Third Symphony, are by Mahler). We knew the masterful Sir Simon's micromanagement and the Berlin beauty of tone would look to the first five movements of the Third's world-embracing epic. But would the sixth flame, as it must, with pulsing inner light and strength of long-term line?

Sir Simon Rattle's clever programming struck again last night, showing us that musical neoclassicism - for want of a better word, which would be something like neo-everything - didn't begin with Stravinsky, whose Apollo ballet is surely his most elevated set of gestures to the past.

It’s the convention to review concerts on the first night of a tour rather than the last, but in this case it transpired it was rather wise to make an exception. These two groups may make very different kinds of music, but in their questing desire to escape classification last night they seemed to share a certain esprit de corps which added to the sense of occasion.

Anything anyone else can do, we can do better, seemed the mantra last night. It's probably a bit churlish to accuse the finest orchestra in the world of arrogance - surely that's their job? But the first night of the Berlin Philharmonic's four-day stay in London (yesterday, the Queen Elizabeth Hall, tonight and tomorrow, the Barbican), in which three of the four pieces required conductorless chamber ensembles, did seem decidedly show-offy.

Too many column inches have been devoted to Percy Grainger’s sado-masochistic sexplay and celebration of blue-eyed Anglo-Saxon supremacy, but it’s his music I love. And have done ever since they celestially sounded the wineglasses for Tribute to Foster, his fantasia on "Camptown Races", at the 1982 Aldeburgh Festival (Britten had been an adoring fan). None of our main orchestras has yet taken up a similar gauntlet on the 50^th anniversary of the Australian-born one-off’s death. So hurrah, in principle, for the smaller-scale enterprise of Kings Place’s four-day festival devised by pianist and Grainger specialist Penelope Thwaites.

It's hard to believe that Yannick Nézet-Séguin could ever turn in a less-than-electrifying concert. According to theartsdesk, he did just that a couple of weeks ago. I wasn't there so I can't comment (though I can credit a rough edge or two).

Their record label describes them rather laboriously as “a Baroque super-group of four superstar Baroque instrumentalists”, but the Retrospect Trio don’t need any fancy titles to prove their quality. Bringing together violinists Sophie Gent and Matthew Truscott (leader of the OAE) and Jonathan Manson on bass viol (principal cello of the Amsterdam Baroque Orchestra) under the direction of young harpsichordist Matthew Halls, this ensemble is all about unshowy musicianship. Joined last night by soprano Julia Doyle they offered up some of the best Purcell London is likely to see this year – with performances from Mark Padmore and the Britten Sinfonia, not to mention Scholl, Jaroussky and Ensemble Artaserse still fresh in the ears, that’s saying something.
