Christian Gerhaher is a classy recitalist. His stage manner is debonair, his tailoring immaculate (although his hair can be unruly). His artistry focuses on key vocal virtues: directness of expression and beauty of tone. In this evening’s recital, an adventurous programme that switched between the Classical era and the Modern, that proved as valuable a combination in Schoenberg as it did in Beethoven.

It was rather like a trip home to see long-lost relatives. Ton Koopman took to the stage at the Liverpool Philharmonic with a broad smile. That smile both greeted the audience and, from what the audience could see, told the orchestra that they were on form. Or, on the other hand, it might have been encouraging them to try harder.

A full house for a premiere performance: Wynton Marsalis bucks the trend in contemporary music. He’s an established name, more for his jazz than his classical work. But in recent years he has produced a substantial body of orchestral music, so the flocking crowds know what to expect. His new Violin Concerto continues the trend. Popular American idioms – mainly jazz and blues – are integrated into a classically oriented orchestral style with an impressive craftsmanship that hides all the joins.

If Omer Meir Wellber is making a bid for Andris Nelsons’s old music directorship in Birmingham, he could hardly have signalled his intentions more audaciously. This concert began with Wagner’s Lohengrin Prelude and ended with Brahms’s First Symphony – basically a surgical strike into the heartlands of Nelsons’s repertoire. And as soloist, he had the Latvian violinist Baiba Skride – an artist who was introduced to Birmingham by Nelsons and who appeared with the CBSO on disc and in concert throughout Nelsons’s tenure.

London foists hard choices on concertgoers. Over at St John's Smith Square last night Nikolai Demidenko was giving a high-profile recital of Brahms and Prokofiev. But since the Prokofiev CD which has had the most impact in recent years has been Freddy Kempf’s, of the Second and Third Piano Concertos with the Bergen Philharmonic and Andrew Litton, a half-full Cadogan Hall seemed like the right place to be, even without Prokofiev on the programme.

“People think when a person becomes old, he has to become serene,” declared that great pianist Claudio Arrau in his mid-seventies. “That’s absurd. The expressive intensity is, I feel, much stronger, much more concentrated in my playing than years ago.” You could argue the same for Stephen Kovacevich at his 75^th birthday concert, though in the case of Schubert’s final, B flat Piano Sonata, was it entirely intensity that had him racing through a work that, back in 1982, he took about 10 minutes longer over, albeit with repeats?

Stanisław Skrowaczewski has become a legend in his own, considerable, lifetime. From the ecstatic ovation as he took the stage, it seemed many were here just to see this iconic figure in the flesh. Fortunately, the performance of Bruckner’s Fifth Symphony that followed fully justified the reception. The interpretation was vibrant and intuitive, with tempo and dynamic decisions seemingly coming from inside the music itself. A few imprecise textural details suggested that age is finally (at 92!) catching up with the great man, but those didn’t matter a bit. This was classic Skrowaczewski.

Sometimes it’s visual art with a sonic slant; sometimes it’s music with a visual slant. Glasgow’s Sonica – created by producers Cryptic, now in its third year and bigger than ever – feels like a thoroughly modern festival, defying genre boundaries and instead focusing squarely on the intersection of the sonic and the visual. That might make some of its offerings hard to categorise, but there’s nothing wrong with that.

For a few very lucky competition winners there is a shopping trip where they are paraded around the world. A terrific opportunity, though a horrible experience, probably. Most competition winners have only a new line in their CV to stare at after the award ceremony, so the advantage of being a 2015 Tchaikovsky laureate, with a promise of an international tour with Valery Gergiev and the Mariinsky Orchestra, is self-evident.
