At last night’s Eurovision Song Contest, host country Denmark submitted “Cliché Love Song”, a weedy Bruno Mars-a-like designed to ensure they did not win for a second year running. It came ninth. While understandable that Danish national broadcaster DR would try to duck the expense of staging the extravaganza in Copenhagen again in 2015, they could have displayed some imagination by choosing an entrant that was certainly not a winner but had some worth.

My preconceived and somewhat misguided idea of the Cabo Verde islands (the official name for Cape Verde these days) was that they were basically a hotter version of the Canaries, with a spare and volcanic landscape that, being a Creole culture in the middle of nowhere, produced a few remarkably wistful singers, most famously the great Cesaria Evora. The islands seem to be a hothouse of tremendous female singers - other purveyors of nostalgic music being the likes of Sara Tavares, Lura and the more cosmopolitan Paris-based Mayra Andrade. 

The March release of North Star, Curved Air's first studio album for 38 years, was no small triumph for vocalist Sonja Kristina and drummer Florian Pilkington-Miksa. Surging yet deliquescent, it echoes here and there the psychedelic pomp of the first three LPs they and original core members Francis Monkman and Darryl Way recorded at the height of the progressive rock era.

Hauschka is a musician and composer from Düsseldorf, performing in what has been dubbed a "post-classical" vein, although he also has many fans in the electronica scene. His new album Abandoned City, written and performed almost entirely on a treated piano, was inspired by the idea of cities that are no longer, or never were, inhabited. It is full of approriately elegiac beauty. Here he introduces the different cities with a paragraph about each.

Three years ago Karol Conka was a receptionist. Since then she had made a living from her music and, with the launch of her first international album Batukfreak, (“Beat-freak”, more or less) is making waves internationally. But that doesn’t tell you the punch her music has or her style (when I meet her, she’s wearing cute Japanese shoes, dyed short blonde hair, super-colourful jacket). Our rendezvous is in Concrete, a small basement club in Shoreditch where she is due to perform her London debut the same night as the opener for London’s always impressive La Linea Festival.

“Art, real art, is a denial of the status quo. A tradition that values the role of the individual.” Speaking in Estonia’s capital for the opening of Tallinn Music Week, the Baltic country’s President Toomas Hendrik Ilves is referring to what’s just over his shoulder. Freedom is on his mind.

It's rare that you can trace a genre to one man. But house music is well documented: “house” originally simply meant the music played at the Warehouse club, by one Frankie Knuckles, who died yesterday in Chicago from diabetes-related complications. Knuckles was a disciple of New York disco, who'd served his DJ apprenticeship in the city's spectacularly decadent gay bathhouses in the mid-Seventies as an understudy of Larry Levan (who would set up the Paradise Garage, which itself gave its name to another genre – garage).

Tina Turner has recorded an album of American blues and folk classics, as well as one original song, with the remaining members of Led Zeppelin. theartsdesk can exclusively reveal that the 74-year-old pop star and soul-funk legend met Led Zep guitarist Jimmy Page through her husband, the German music executive Erwin Bach, and that recording took place last November near her home in Küsnacht, Switzerland.

It’s strange to think that music recorded 45 years ago in what was once an old Yiddish theatre turned rock 'n' roll palace on the Lower East Side in the summer of 1970 – a few months before Jimi Hendrix’s death, as war raged in Vietnam and riots in the US – still sounds way ahead of our time, let alone the time in which it was made.

Bernd “Burnt” Friedman is one of the most relentlessly questing of experimental musicians. In over 30 years of making music and 25 years of releasing it, he has specialised in researching ancient, hypermodern and as-yet-undiscovered methods of soundmaking, including traditional and home-built instruments and the application of high-tech methodologies to established forms from around the world, in particular jazz, western club sounds, and African and Japanese styles.
