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.

The French national holiday of 14 July might be marked by parades and fly-pasts in Paris, but here on the Atlantic coast it’s the central date for Francofolies, the annual festival dedicated to French music. La Rochelle hosted its first Francofolies in 1985. Twenty-six years on, the festival remains the premier showcase for Francophone music. This year the bill took in David Guetta’s dance-floor cheesiness, Gotan Project's overhauled tango, actress Mélanie Laurent plugging her recent album and all points in between.

This is where the delirium kicks in. Tired but happy, the attendees started the third day of Sónar festival slightly boggled by how to pick and choose from the strange delights on offer. Saturday was when the true musical variety of the festival was displayed: straight-up hip hop to eye-popping South African tribal dance displays, balmy ambient revivalism to apocalyptic techno, heartbroken electronica to deranged prog rock: it was all on offer...

Following in the stilettoed footsteps of Lady Gaga’s extended-play reissue of her platinum-selling The Fame, Take That’s Progressed is a two-disc repackaging of the November 2010 Progress album featuring eight additional tracks. With its menacing disco beats and penetrating falsetto vocals, it is an evolution to be proud of.

This series of albums is the sound of one of the most epochally important producers in soul and dance music history reworking his magic. The closest analogy I can think of that non-dance music fans would appreciate is The Beatles' Love album in which George Martin went back to the master tapes and not so much remixed as recreated their work, but there is none of the whiff of superfluous tinkering here that that project had.

If, as the cliché goes, hardship begets soulfulness, then given her life story between her 2008 debut and this (Wikipedia can provide the details if you're feeling ghoulish), Jennifer Hudson should now be the new Aretha.

Frothier than a zero-gravity cappuccino, camper than a gay pride march through Brighton, cheesier than all the fromageries in France, and with almost as many beats per minute as a hummingbird’s heart: Kylie is back with a brand new show, and it’s quite something. Others will doubtless have rolled out the statistics – that it cost £530 million to stage, is built and staffed by a crew of 7,000, and requires a fleet of trucks that would stretch from London to Luton to keep it on the road. Or something.

The Sónar festival occupies a very special place in the New Music calendar – and is this year expanding outwards temporally and geographically, with new franchises in Tokyo and A Coruña, Galicia. Now into its 17th year, the parent festival in Barcelona serves as a vital meeting point for those of all stripes who refuse to acknowledge the polarisation of avant-garde and populism, or of club culture and the mainstream music industry. With 10 or more main stages and untold off-piste club events around the city, it would be impossible to condense even a single day and night of Sónar Barcelona into a standard gig-venue show, but that's what A Taste of Sónar tried to do last night.

Let's get the obvious out of the way: yes, this is incredible. Not just the sounds, nor the ambitious staging of Hans Christian Andersen's last story as a ballet, but the fact that, 30 years since they met, Neil Tennant and Chris Lowe are still making music that's both relevant and gloriously excessive to a frankly crackerdog mental degree. They've tinkered with classical themes before, of course, from setting “Che Guevara and Debussy to a disco beat” in 1988's “Left to My Own Devices” to their 2004 live soundtrack to Battleship Potemkin, but this is something else. Piling on romantic themes and electronic beats of various flavours, it leaves no stone unturned in finding the most over-the-top fairytale themes, then ornamenting them and ornamenting the ornamentation of the ornaments until the whole thing is a kaleidoscope of whirling, twirling synaesthesic madness.
