When Alfred Brendel first mentioned Kit Armstrong to me, in early 2008, I knew there was a film there. He was brimming with excitement: Kit had come to him with an interpretation of a Chopin Nocturne that displayed a command and maturity that was baffling considering Kit was 13 at the time of the recording. Alfred led me into his inner sanctum, a practice room filled to bursting with two Steinways, a large carved idol from New Guinea, Liszt’s death mask and a rich and varied collection of paintings and images, some of them revealing the pianist’s wicked Dadaist sense of humour.

Cambridge University, cradle of Newton, Keynes and Wittgenstein, of Wordsworth, Turing and Tennyson, has produced 15 prime ministers and more Nobel Prize-winners than most nations. In its 200-year history, the university’s debating society has hosted princes, politicians and leaders in every field: the Dalai Lama, Winston Churchill, Nelson Mandela, and last week a 25-year-old east-London DJ, Kissy Sell Out.

It’s Holy Wednesday in Cuenca, and going round the corner into Cathedral Square I’m surrounded by hordes of guys in multicoloured mufti who look like the Ku Klux Klan, with unnecessarily pointy hoods. Twenty of them are carrying a heavy float with a large statue of Jesus on it. In Cuenca things are fairly austere, compared to other places where there’s a lot of self-whipping, or where, if you have sin on your conscience, you may end up banging nails into your hands, as in Mexico. Still there are alternative amusements – the Copa Del Rey final of Real Madrid v Barcelona is blaring out of bars – and it’s the 50th edition of Cuenca’s Religious Music Festival.

In the later 19th century, violinist and composer Joseph Joachim was hailed as the most brilliant fiddler of his day, but today his name lives on via the great works that he helped to bring into the classical repertoire. Brahms dedicated his Violin Concerto to Joachim, while Bruch's First Violin Concerto was substantially revised by Joachim and became closely identified with him. Both the Schumann and Dvořák concertos were written for him, though Joachim never performed the latter.

A new recording of The Goldberg Variations is now available, by Nick Van Bloss. In the annals of British pianism, it’s not quite a name to be conjured with. Or not yet. Until he performed at Cadogan Hall in 2009, he had not visited the concert platform in 15 years. After a promising early career, he retired at the age of 26. It’s not as if he didn’t play the piano at all in the interim. He just didn't play to anyone but himself. The reason why he gave up performing is simple. Van Bloss suffers severely from Tourette’s syndrome.

UPDATE 2015: Four years ago, in January 2011, I wrote this article about the music critic and biographer Michael Kennedy's search for the missing portion of Elgar's life. It identified a Mrs Dora Nelson as the composer's mistress and mother of a lovechild, who might have influenced some legendarily enigmatic aspects of Elgar's compositional output. A new development opened when an Arts Desk reader contacted me, who had taken up Kennedy's and my requests for others to pick up this unsolved mystery.
