As pianist Beatrice Rana ran up the final bars of Schumann’s Piano Concerto, the conductor Mirga Gražinytė-Tyla turned to her soloist and simply beamed. As well she might. Rana is an artist whose advance publicity belies the seriousness and selflessness of her playing. Her Schumann didn’t concern itself with flashy effects (though there were some daring variations of tempo) or even, particularly, beauty of tone (though the iridescent glow she gave to the little cascades of chords that link the Intermezzo to the finale showed that she commands an impressive palette).

So the feasibility study for the new concert hall – The Centre for Music – has finally surfaced, a little later than planned. It’s being greeted, generally speaking, as if it’s to be the next London Olympics. “A global beacon,” declares the Evening Standard... Nicholas Hytner (he who said that building the Southbank Centre extension would spoil the view from his National Theatre) compares it to Tate Modern, which he says enlarged audiences for other visual arts rather than taking them away. This should, he says, be “a Tate Modern for music”.

You can read a lot into the first two chords of Beethoven’s "Eroica" Symphony. Classical portico or violent detonation? Majestic assertion of E flat major, or the first shocking glimpse of a drama that’s already under way? Michael Seal, conducting the City of Birmingham Symphony Orchestra, accelerated through those first two bars before sweeping into a sleek, swinging first subject. He could afford to let his players sing. Those asymmetrical opening chords had done just enough to subvert the polished surface – to hint at the music’s latent potential for violent disorder.

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.

Cards on the table: the City of Birmingham Symphony Orchestra is looking for a new music director. Having filled its new season with emerging talents – Andrew Gourlay, Daniele Rustioni, Ryan Wigglesworth and Ben Gernon, to name just four – it’s an open secret that any concert directed by a youngish, more-or-less unattached conductor in Birmingham for the foreseeable future is effectively an audition for the job. And don’t let anyone tell you otherwise.

This Prom was the final concert of Andris Nelsons's remarkable seven-year spell as principal conductor of the City of Birmingham Symphony Orchestra. Their Prom showed the astonishing level of responsiveness and flexibility which he and they have achieved together, over the course of more than 300 concerts.

If Simon McBurney’s Measure for Measure for the National Theatre and Declan Donnellan’s recent Cheek By Jowl production mined deep for darkness, Dominic Dromgoole’s for the Globe is content to skim the play’s sunny surface – the comedy manqué that Shakespeare didn’t quite write. It’s a decision that makes sense of a difficult work on the Globe’s own terms, playing to a summer crowd, but one that also generates its own confusions and inconsistencies.

This was a very "concert" performance indeed. Across the stage music stands stood like sentinels lest any rash singer attempted to stand out and – surely not – act. Such fears were misplaced (or the stands did their job) in the end, as the music was what mattered and everyone stood and sang, with one outstanding exception, the Kundry of Mihoko Fujimura.

A trio of Rosenkavaliers: what more could one want as we near Richard Strauss’s 150^th birthday? Well, more of the less often performed operas, for a start. But as this is the Straussian cornucopia, it’s not going to tire those of us who love it beyond reason, and Andris Nelsons’ concert performance with his devoted City of Birmingham Symphony Orchestra eventually delivered as much in its rather peculiar way as the Barbican excerpts earlier this month and Richard Jones’ gobsmackingly original, disciplined take at Glyndebourne.

“Did he who made the Lamb make thee?” Blake asked the tiger. One might have asked the same question of Scriabin’s Poem of Ecstasy, with Mozart’s G major Piano Concerto, K.453, as the lamb, in this hyper-diverse Birmingham concert. The image of divine simplicity was in the delicate hands of Mitsuko Uchida, whose Mozart resisted every striped temptation that Andris Nelsons and the CBSO threw in her path.
