Just a week left at the lovely Dulwich Picture Gallery to take a look at the astounding career of MC Escher. Every poster-owning student knows the Dutchman’s ability to create mind-bending shifts of perspective so that water flows upwards and stairs descend to higher levels. But this exhibition shows he was so much more than a trickster. The first room contains a set of early portraits which demonstrate his brilliant draughtsmanship. The highlight of the middle section is a simply sensational self-portrait in a spherical mirror. And in the final room, providing a more than fitting finale, is his gorgeous take on the effect of ripples on water and another of a reflection in a puddle. The whole reveals him to be not just the greatest graphic artist since Durer but something close to a genius. See it!

Intriguing exhibition at Tate Modern of sculptures by Alexander Calder, the man who invented the modern mobile – and I’m not talking about telephones. His early wire portraits of friends such as Josephine Baker and Joan Miro are extraordinary for their technique as much as their revelatory qualities. But once his work had lifted off and ceased to be static thanks to either through breeze-power or an electric motor it moves on to a higher plane in every sense. Some of the later mobiles (a description coined, almost inevitably, by Duchamp) are quite simply out of this world. The show runs till April 3

If you’re ever in the beautiful city of Salzburg, do yourself a favour and book a Mozart dinner in the extraordinary Barocksaal of St Peter Stiftskellar – your five senses will love you for ever. Not only did I have a great meal based on recipes from the 18th century but I was treated to a recital by members of the brilliant Amadeus Consort: soprano Karolina Plickova, baritone Ludovik Kendi, violinists Martin Osiak and Nela Mendelson, violist Mladen Somborac, cellist Simon Nagl and, on the double bass, Thomas Fuschelberger. They performed excerpts from The Marriage Of Figaro, Don Giovanni and The Magic Flute – and it really couldn’t have been more magical. I can’t recommend it highly enough.
