Six weeks in and we’ve got to that sweet spot in the Proms season where thematic threads start to knit together, sequences begin to fill out, cycles to finish – when you hear not just the concert in front of you but the echoes of those already past. It’s this cumulative impact, this sense of narrative that gives the festival its particular character, lending weight to even the most workaday midweek concerts.

Everything you may have read about Mirga Gražinytė-Tyla's wonder-working with her City of Birmingham Symphony Orchestra is true. Confined to a Turkish hospital bed when their first Prom together took place last August, I wondered from the radio broadcast if the extremes in Tchaikovsky weren't too much. In the live experience last night, the miracle of the detail and the justification for even the most startling decisions proved totally convincing.

Reformation Day, Luther 500 - in Proms terms it can only mean Bach, the alpha and omega of music, flourishing roughly two centuries after the Wittenberg Nightingale nailed his 95 theses to the church door.

From sunset to sunrise, across aeons of time, usually flashes by in Schoenberg's polystylistic epic. Not last night at the Proms: Simon Rattle is too much in love with the sounds he can get from the London Symphony Orchestra - here verging on a Berlin beauty - to think of moving forward the doomed love of Danish King Waldemar and the beautiful Tovelille.

It was an intriguing, contrast-filled programme that Swiss-born pianist Andreas Haefliger brought to Edinburgh for his Queen’s Hall recital at the International Festival. Two masterpieces of musical picture painting – Mussorgsky’s Pictures at an Exhibition and the smaller but equally evocative St Francis of Assisi’s Sermon to the Birds by Liszt – alongside two far more abstract works: Berg’s compact but punchy Sonata Op.

So it was Rachmaninov night at the Proms, but with a difference: a trinity of works sacred and profane, the first two introduced by the Latvian choir due to perform the third singing harmonised Russian Orthodox chants of the kind on which the composer based so many of his supposedly late-romantic inspirations. That was bound to enliven a bog-standard programme of the Third Piano Concerto and the Second Symphony.

Goodness the BBC Philharmonic plays well for John Storgårds. The orchestra’s chief guest conductor has a lovely easy manner on the podium – all curved gestures and loose arms, and the result is a partnership that brings the absolute best out of the BBC’s Manchester-based orchestra.

The road to hell is paved with brilliant ideas in Berlioz's idiosyncratic take on the Faust legend.

A Prom of unrelenting momentum began promisingly with Beethoven, and the false start that opens his First Symphony. On this showing, Kirill Karabits has coached his Bournemouth musicians in the classical repertoire with a dash and flair that brings to mind a golden era for the orchestra under the stewardship of Rudolf Barshai in the 1980s.

Before reuniting us in high spirits with a pair of much-loved old friends, Mozart's Sinfonia Concertante and Brahms's Second Symphony, the Deutsche Kammerphilharmonie Bremen under Paavo Järvi at the Proms took us into a darker, and unexpectedly affecting, place.
