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.

This is the second Sunday in a month that I've sat in the Wigmore Hall and been plunged into an evening of ferocious concentration from the very first bars. Mid-January saw violinist Leonidas Kavakos and his phenomenal pianist Enrico Pace carving out the grim memorial that is Prokofiev's First Violin Sonata, ultimately softened by radiant Schubert. Last night Kavakos's peer Thomas Zehetmair accented the lead in late Beethoven, and since only Shostakovich's last quartet followed, this time there was to be no more human gilding of a very alien lily.

Something of a bad boy in the Baroque world, Philip Pickett can generally be relied on to provoke discussion. Whether it’s by teaming up with one of Rolling Stone magazine’s Greatest Guitarists of All Time, or restaging Purcell’s The Fairy Queen with tumblers, jugglers and an excess of hand luggage, there’s always an angle. While collaborators, contexts and repertoire may change, what you can generally set your watch by is the quality of the musicianship – which made last night’s concert all the more of a puzzle.
