How to judge a genius who died at 25? Gerald Larner, in his programme note for this concert by the City of Birmingham Symphony Orchestra, suggests that Lili Boulanger’s tragically early death was actually central to her achievement. She knew she probably wouldn’t see 30, and directed her energies accordingly.

Questions of interpretation apart, Simon Rattle has yet again proved the great connecter, this time in concerts separated by just over a month.

Singing satirist Anna Russell placed the French chanson in her category of songs for singers "with no voice but tremendous artistry". Mezzo Karen Cargill has tremendous artistry but also a very great voice indeed, a mysterious gift which makes her one in a thousand, and also rather good French (put that down to Scotland's "Auld Alliance, perhaps).

Let's face it, Robert "Cabinet of Dr Caligari" Wiene's 1926 film loosely based on Strauss and Hofmannsthal's 1911 "comedy for music" is a mostly inartistic ramble. Historically, though, it proves fascinating.

First the good news: Cédric Tiberghien, master of tone colour, lucidity and expressive intent, playing the 24 Chopin Preludes plus the Bach C major and the C minor Nocturne in the red-gold dragons' den of the Royal Pavilion's Music Room.

The BBC Young Musician final was a big event in Birmingham. It drew a capacity audience to Symphony Hall, as enthusiastic, engaged and encouraging as any of the competitors could have wished. After the prodigious talent on show in the section finals, it was no surprise that the standards here were sky high. Fortunately, the three finalist were also born entertainers, making for an enjoyable, though excruciatingly hard to call, competition.

After Pierre-Laurent Aimard’s first concert in his weekend Ligeti festival at the Southbank, an innovative programme spanning influential contemporaries and new arrangements, this second was a more canonical affair: the three books of Piano Études presented in recital.

The mini-festival of György Ligeti’s music this weekend at the Queen Elizabeth Hall kicked off with a concert of chamber music that moved from a monumental first half to a second that was a delightful unbroken sequence of miniatures.

This is the 50th Vale of Glamorgan Festival, and as its founder and director, John Metcalf, reminded us in a brief post-interval speech, he has been at all of them.

When you have 21 women to present in song, but only a couple among the 14 poets and none to represent them out of the 15 composers idolising or giving them a voice, you need two strong defenders of their sex at the helm. Lucy Crowe and Anna Tilbrook are no shrinking violets – the soprano no longer a light lyric, the pianist supportive only in the best sense, full of flexible power and forceful middle-to-lower-range sonorities for the voice to coast above.
