Just as our brief, premature spring collapsed into the bluster of Storm Freya, the Enlightenment certainties of Haydn’s more dependable cycle of nature blew into the Royal Festival Hall. Perhaps because its lovely but (for the most part) serene music tends to occupy the sunlit uplands, The Seasons has never quite secured the automatic respect accorded to the cosmic and human drama of its immediate forerunner, The Creation.

The Endellion Quartet first rehearsed on 20 January 1979, deep in the throes of Britain’s so-called “Winter of Discontent”. That longevity – with three of the original players still on the team after four decades – makes the acclaimed ensemble roughly as old as Spandau Ballet, and senior to REM.

Two successive nights, two contrasted solo keyboard recitals at the Wigmore Hall: not great for the knees but marvellous for the soul.

Missa in Angustiis. Mass in troubled times. There was a logic in programming Haydn’s D minor Mass on the Armistice Centenary day. The final words of the mass, dona nobis pacem, would be the right ones to end this day of reflection.

There’s always a special atmosphere when the City of Birmingham Symphony Orchestra returns to Birmingham Town Hall, and it’s not just because of the building’s Greek Revival beauty: the gilded sunburst on the ceiling, or the towering, intricately painted mass of the organ, topped with its cameo of Queen Victoria.

There is a tide in the best-planned festivals that comes in and out almost imperceptibly, bringing with it changes as the days move on. Put it down to the kind of perfect planning that discards any one rigid theme, and to forging long-term links with performers who don't just pop in for one concert.

In the right hands, the music of the various Viennese Schools can still sound almost startlingly original. Imogen Cooper’s are very much the right hands, containing a rare, refined artistry that only continues to grow with the years.

Haydn: Piano Sonatas 32, 40, 49, 50 Paul Lewis (Harmonia Mundi)

Say what you like about Mirga Gražinytė-Tyla’s partnership with the City of Birmingham Symphony Orchestra – and plenty has already been written – but sometimes the facts speak for themselves. At the end of this midweek matinee concert, an audience that had presumably been lured by the promise of Haydn and Max Bruch exploded in laughter and cheers at the end of a piece by György Ligeti.

Power and intelligence combined make Sarajevo-born British pianist Ivana Gavrić stand out from the crowd. Bass lines are clear and strong; right-hand melodies move in keenly articulated song. The first half of her recital progressed with well-earthed, dancing energy to a strong clincher in Chopin's B flat minor Scherzo.
