Despite their different paths in the Seventies, the final years of the Sixties saw parallels between Betty Davis and Jeanette Jones. Both soul singers had significant backing from music business insiders. Late in the decade, each had a discography limited to one unsuccessful single. They worked as models.

A two-bar flurry of guitar lays the table for a skip-along beat, handclaps, and an arrangement and melody akin to Martha and the Vandellas’ March 1964 single “In my Lonely Room”. This though was not a Motown production and did not tell the story of a girl so distraught at her boyfriend’s dalliances that all she could do was take to her lonely room and cry. On “The 81”, Candy & the Kisses sang of a dance craze for anyone “tired of doing the monkey, tired of doing the swing.”

Sixty-five thousand people came to Wonder. The final night of British Summer Time in Hyde Park was a sell-out. With a performance lasting four hours including an intermission, the Detroit-born legend and his band – and also the weather, which stayed fine all evening - can have left nobody disappointed. The show, based on the album Songs in the Key of Life, with some extra off-piste excursions, was thoroughly convincing live. It just works very well, and on several levels. 

The year 1987 was a notable one in music history. In February, Burt Bacharach won the Grammy for best song with “That’s What Friends Are For”, and two months later Joss Stone was born in England. At the age of 17 Stone would be nominated for three Grammies of her own, and at 19 would become a winner. She remains a platinum-selling singer and songwriter at the top of her game.

If last night made anything clear it's that some things are still some way beyond the reach of hipster reappropriation. The audience in Hyde Park for Carole King was 99% white and middle-aged, with the very few younger people scattered about appearing to be teenagers there with their parents.

It begins with “Never Never Let Me Down” by Formulars Dance Band. “You’re the only good thing I’ve got,” declares the singer of a garage-band answer to The Impressions over a rough-and-ready backing where a shuffling mid-tempo groove is driven along by wheezy organ and scratchy lead guitar. When the band unites to sing harmonies, the massed vocal is distorted: a sure sign of an overloaded microphone. If this were America, “Never Never Let Me Down” would have been an obscure independent soul release issued around 1966.

It’s a foolish game to wonder who might fill the musical void left by Amy Winehouse’s passing. She was a one-off, after all. However, it’s natural to occasionally look about and ponder where there might be talent of a similar ilk. Not all the doomed druggy stuff, just a female singer who does it from the gut rather than X Factor-flavoured fluffing.

The first reaction to Introducing Karl Blau is to wonder whether it’s an overlooked album from the late ‘60s or early ‘70s. It opens with a creamy smooth voice that’s close to cracking with emotion. The song being sung is a version of country singer-songwriter Tom T Hall’s “That’s How I Got to Memphis” which sounds as though it was recorded at Alabama’s FAME studios at least 45 years ago. With gently funky guitar, shuffling drums and a slightly deeper vocal register, the next track, “Six White Horses”, bears the influence of Tony Joe White.

Corinne Bailey Rae’s heart may speak in whispers, but it dreams in glorious technicolour. The title of the Leeds-born songwriter’s new album is an echoey chorus line that swims among the layers of its opening track – a song with the bridge of a boiling ocean that hints at dance-pop beats, reinvention. “The Skies Will Break” was surely an album title contender in its own right, perhaps not so much for its dubious poetry as for the glorious moment of catharsis it signals – a head rush, and then a moment of serenity.

Canadian singer/producer Jessy Lanza's records – and this one more than ever – can feel like they're mapping an alternative history, one where populist and leftfield electronic music were never separate. Two aspects dominate her sound: her crisp, clear pop vocal, and a palpable love of the sonorities of drum machines.
