We're packed into the basement of Madrid's Costello Nite Club, a kind of narrow brick-lined tunnel off the Calle Gran Via. It's the kind of place where you could imagine finding groups of earnest jazzniks nodding along to atonal pandemonium in 11/7 time.

David Nice writes: it hardly seemed possible, but a pivotal figure in the 20th century music scene has died, two months short of his 91st birthday. As composer, Boulez now seems not so much a game-changer as a constant innovator in one of many strands among the possibilities of contemporary music. He even admitted in an Edinburgh Festival interview that he and his colleagues may have underestimated the role played by the audience in absorbing his avant-gardism.

Jaap van Zweden is going places. At 55, he is already 16 years into a second high-profile musical career. His first, as a violinist, saw him appointed leader of the Concertgebouw, the youngest ever to hold the position. From there, he moved to the conductor’s podium, and is now Music Director of the Dallas Symphony and the Hong Kong Philharmonic. According to some rumours, he is also under serious consideration for the New York Philharmonic.

Long before the Swiss came to dominate the watchmaking world, British horologists were leading the way, grappling with miniscule screws and the vagaries of time. In the eyes of many collectors and aficionados they still are, thanks to Roger Smith, who spurns quartz crystals and mass production techniques to produce exquisitely crafted mechanical timepieces almost completely by hand.

The Forbidden Room, reviewed here yesterday, brings to a climax Guy Maddin’s thirty-year orchestration of the ghosts of world cinema past. A movie like no other, it’s a hectic, twilit construction and deconstruction of What Might Have Been: a pullulating assemblage of vintage movies that were either lost or never made reinvented by the Canadian filmmaker and his co-writers Evan Johnson and Robert Kotyk.

Glasgow has a brand new concert hall, and the Royal Scottish National Orchestra has a brand new home. A move for the Orchestra from Henry Wood Hall, a converted church in the city’s West End it has occupied since 1979, has been on the cards for several years, but few could have predicted the scale and intricacy of the final project. The New RSNO Centre snuggles conveniently right next to the Glasgow Royal Concert Hall, and brings new offices, an education suite, a digital centre and practice rooms right to the city centre.

Last month, Ludovico Einaudi's album Elements debuted at No 12 on the UK album charts, which made it the highest-charting modern classical album since Henryk Górecki's Symphony of Sorrowful Songs reached No 6 in 1992. It was proof of the quietly burgeoning allure of Einaudi, which has been stealthily expanding around the world since his first solo release, 1988's Time Out.

Eska Mtungwazi (b 1971) was born in Zimbabwe and grew up in Lewisham, south London, her early musical tastes inspired and shaped by her father’s vinyl collection, and her experiences singing both church music and in classical ensembles. She studied Maths originally, and has built a career incrementally, spending ten years as a session musician, and accumulating generic and stylistic influences which have shaped her hugely varied act.   

Patrick Barlow’s last play was parked in the West End for nine years. The 39 Steps finally closed this autumn, but not before travelling all over the world, most prestigiously to Broadway but also, among other destinations, to Russia, Japan, Australia, Korea, Hong Kong and France. There have been no fewer than eight different productions in Germany, including one with an all-female cast. So the question naturally pinging around Barlow’s cranium was: how exactly do you follow that?

“He has been in poor health for some time, but was cracking jokes to the last,” read the statement from Warren Mitchell’s family following news of his death today, at the age of 89. That will come as no surprise for those who remember the actor primarily as Alf Garnett, first in Till Death Do Us Part (on the BBC, 1965-75), and later In Sickness and In Health (1985-1992).
