The songs of Jacques Brel and Juliette Gréco are old friends. She has revisited them many times since she began performing with Brel’s former accompanist, the pianist Gérard Jouannest, in 1968. Brel and Jouannest had worked together since 1958. Gréco married Jouannest in 1989. Gréco Chante Brel features him on nine of its 12 tracks. As well as being integral to what it is to be Gallic, the album can be considered a family affair.

Although Confection is sonic ear-candy of a most seductive type, it’s hard to grasp what the point is. The album is lush, orchestrated and enfolding, but it does nothing new and says little beyond being the product of meticulous craftsmanship. Essentially, it’s the soundtrack to a film that does not exist. Themes are stated and then restated. A half-time interregnum comes with a playful synth outing which could be an alternate theme to the Magic Roundabout.

The ICA was the perfect location for the UK debut of hotly tipped new duo Tomorrow’s World, consisting of Air’s Jean-Benoit Dunckel and English synth-rockers New Young Pony Club’s ivory tickler Lou Hayter. The venue added a prestigious edge to what promised to be an auspicious occasion. A scant crowd suggested this was more of a test run than a full-blown debut, but they needn’t have worried about the reaction. Their music spoke for itself.

The Gainsbourg-Birkin dynasty is akin to a gift that keeps on giving. Just when it appears to be dormant, another member of the extended family reveals a new role. Lou Doillon, daughter of Jane Birkin and film director Jacques Doillon, is best known as a model and actress. Last September her debut album, Places, was released in France and its belated arrival over here is sure to make a few waves. Hopefully not because of who she is, but due to it being first-rate.

"Stately" is the best adjective for Françoise Hardy’s similarly measured follow-up to 2010’s La pluie sans parapluie. Fifty-three years on from her first release, there is no need for Hardy to break new ground or hare off on a tangent, but her regular release schedule suggests a contentment with sticking to what she knows best. That stretches to the creation of the album itself, where the lyrics are mostly hers but all the music is composed by others. As a pioneering singer-songwriter, it is sad this aspect of her creative self has been surrendered.

Definitely not the M that hit with “Pop Muzik” in 1979 and then swiftly vanished. This –M- is a bona fide, stadium-filling superstar. In France, that is. In Camden though, last night, Mathieu Chédid confounded any expectations of what stadium rock ought to be. The evening was rounded off by Chédid and his band dancing in a line to a playback of last year’s single “Mojo”, just as they’d done in the video. They make open and shut gestures with their hands, mimicking a mouth. The audience do the same.

“Cut Copy me”, the opening track of Petula Clark’s first British studio album in six years, is beautiful. It could have been created by Saint Etienne at their most melancholy. Her voice almost a whisper, it’s the sound of shadows and uncertainty even with what sounds like a light touch of autotune. The title track follows. Similarly assured, it’s sparse and centred around a rippling piano. Then a by-rote, in-the-shadow-of-Adele version of Gnarls Barkley's "Crazy" breaks the spell.

The notice saying “table reserved for Lord Chelsea” in Cadogan Hall’s foyer bar instantly signalled this show was likely to be more rarefied than your normal pop concert. It was in keeping with the grandeur of this early 20th century, Byzantine-style former church a minute from Sloane Square. The tone was further elevated by this being a rare, small-venue British outing for Jane Birkin, an actual, proper star.
