The time is out of joint for Turkey at the moment, but it’s still a country equally split between those looking to the west for the culture of ideas and the more conservative element which at least needs its voice respected. They co-exist peacefully in a great cosmopolitan city like Istanbul, which recently joined Ankara and Izmir in rejecting increased powers for its leader.

"Generally speaking," writes Evgeny Kissin in one of the many generous tributes to those whose artistry he most admires, "the mastery of [Carlo Maria] Giulini is exactly what is dearest of all to me in art: simplicity, depth and spirituality". The same is true of the personality revealed in this slim but by no means undernourishing volume from one of our time's most fascinating pianists.

Liam Scarlett must be worked off his feet. Just at the Royal Ballet, he made a full-length work, Frankenstein, last year and is currently working on a new Swan Lake; and now last night he has premiered a new abstract work, Symphonic Dances at the Royal Opera House.

The Hagen Quartet has been playing together for decades, and it shows. The group, which includes three siblings, performs with a deep and intuitive sense of unity: of timbre, technique, articulation and intent. Where most quartets are clearly led by the first violin, the Hagens move as one, the motivation coming simultaneously from each player. They put this finely honed ensemble to the service of emotive performances, but also retain a sense of intimacy and proportion.

As a scan through the 17-year list of Rosenblatt Recitals quickly reveals, sopranos and tenors come and (often as not) go. Much rarer is the opportunity to enjoy the gifts of a mezzo-soprano near the start of what should, all things being equal, be a long and illustrious career.

Restlessness in a good sense was the keynote of Elisabeth Leonskaja's latest revelatory recital.

The cello is so deeply engrained in my fingers, my imagination, it’s part of my being – my life would feel amputated without it. You fall in love with the instrument, the music, and then you embark on the life-long task of trying to get closer to that beguiling musical ideal. That’s the drug, the contract you sign with the devil. Every day I think how lucky I am that I can dive into a score and work at it physically.

Has any living pianist had a richer or more charmed life than Idil Biret? As a child prodigy she studied in Paris with Nadia Boulanger and Alfred Cortot, and both there and in Germany with Wilhelm Kempff. At the age of four she was reproducing Bach Preludes and Fugues on the family piano in Ankara simply from hearing them on the radio. When she was seven the Turkish Parliament passed "Idil's Law", enabling not her but also other gifted children to study abroad.
