Pop music was virtually eradicated from Iran in 1979 after the deposition of the Shah and arrival of Ayatollah Khomeini in power. Before then, the thriving scene supported many stars that drew on both local traditions and Kurdish music. Googoosh was a huge star, but she stayed in Iran after 1979 and was unable to record. Moving to Los Angeles in 2000 allowed her to perform and begin recording again. The arrival of a new British compilation covering 1970 to 1975 is fascinating. It includes some incredible, head-turning music too.

Amy Winehouse, who was found dead at her London home this afternoon, was the greatest female pop singer of her time, in the way that Billie Holiday was of hers, says Peter Culshaw, the first of theartsdesk's writers who tell below what she signified to music and to them. More tributes come from Joe Muggs, Thomas H Green, David Nice and Matilda Battersby.

Lucian Freud, who died aged 88 at his west London home on Wednesday, was often described as Britain's greatest living artist. In the six decades he was active, figurative painting went in and out of fashion - though mostly it was out - but Freud remained resolutely outside and beyond fashion. As both an art world grandee and something of a celebrity, he really had no rival, though perhaps David Hockney, still alive and 15 years his junior, came closest. Freud, however, had a very different way of looking: cooler, harder, more penetrative. Below, four writers pay their personal tributes.

Whatever the quality of the material with which they're grappling, there are two undeniable truths about the Belarusian actors who've put their already curtailed freedom on the line by coming to the Almeida Festival this week: they're skilled practitioners of their art and courageous human beings. Read their biographies in the programme and you'll see that the words "detained", "arrested", "attacked", "dismissed" crop up rather a lot. In Europe's last dictatorship, stepping out on stage and speaking a line, a word even, can lead to imprisonment.

The nominations for the 2011 Barclaycard Mercury Music Prize were announced earlier today. Beyond PJ Harvey and Elbow having won before, nothing wildly surprising cropped up.

Tonight the doors open for the biggest classical music festival in the world, the BBC Proms at the Royal Albert Hall. To help you plan your summer visits and listening, theartsdesk's critics gently steer you with their own preferences from the 90 concerts on offer. You can also check the complete list of all Proms on another page.

It's 50 years since the mighty Kirov Ballet made their debut London tour - reeling from Nureyev's defection days before at the Paris airport. The tour was promoted by the unique impresarios of Soviet culture, Victor and Lilian Hochhauser. Half a century on, the pair are still indefatigably promoting the company, now named Mariinsky Ballet, whose season at Covent Garden opens on Monday, 25 July and runs to Saturday, 13 August.

Sweetheart American mezzo Joyce DiDonato stayed firmly behind the proscenium arch for yesterday evening's Royal Opera performance of Massenet's Cendrillon - reviewed by theartsdesk on its opening night - but another Covent Garden regular, former ballerina and non-irritant presenter Deborah Bull, was soon schmoozing the crowds in Trafalgar Square, assembled to watch the fairytale unfold in real time beneath Nelson's Column. It was a big occasion for the long-deceased composer, who having enjoyed short-lived fame went into near eclipse except for Werther and Manon over the next century but last night supposedly had 50,000 pairs of eyes up and down the UK on one of his most delicate creations courtesy of the free BP Summer Big Screens.

Interesting movie news. Arnold Schwarzenegger, having wrapped up his term as governor of California and pretty much completed the bankrupting of the state, will be taking time out from impregnating the payroll to return to the day job: making movies. The film is to be called The Last Stand. Make of that what you will.

The weekend of 29 to 31 July will see London's Festival Hall transformed into what the venue describes as a “multi–venue vintage playground”. Vintage, founded by Wayne and Gerardine Hemingway, comes to London for the first time to celebrate the popular culture of Britain’s past. The Festival Hall is a fitting host, as it was constructed for 1951’s Festival of Britain and is, itself, a piece of living history.
