We go out of this column's comfort zone for this week’s releases which include orchestrated versions of songs by the Fab Four, and an Italian pianist’s imaginative response to jazz god Thelonious Monk. And there’s also some Led Zeppelin played by a string quartet.

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.

Nat Baldwin’s alt cred is impeccable. Not only is he a former bassist for Brooklyn’s über-cool Dirty Projectors, he’s also responsible for a string of releases that began with 2003’s free jazz set Solo Contrabass. Also prepared to take a stroll with the less cool, he’s been heard on a TV ad for Orange mobile phones, the one with the barefoot, ladder-descending lady. Although People Changes worms intimately in, it’s hard to detect a singular voice. Formerly in thrall to Anthony Braxton, he’s now trying on Arthur Russell.

It's always interesting to see how revolutions in music get folded back into the fabric of the culture that fomented them. Dubstep, which changed club culture so dramatically in the mid-2000s, is now an intrinsic part of that culture from mainstream to margins, and the forms it takes as it beds into these various parts of the ecosystem are manifold. And Jazzsteppa – two Israelis named Gal and their trombones – turn their hands to a fair few of those forms.

I never thought I’d find myself saying that a French female vocalist reminded me of Howard Devoto. But there we are, what can you do? There’s just something in the way she sings the verses of “Hell be Damned and Look Out”: the pauses between words (“Let’s face it… you may only live… once”); the way the last note (word) of the line just kind of hangs there, emotionally ambiguous and philosophically inscrutable. But Florence Joelle also has the sensuous purr of a French Marilyn Monroe. So whichever way you look at it, you’ve got to sit up and take notice.

“In jazz music you have the freedom, you have the expression. You have the visceral and you have the intellectual. Everything can be expressed through jazz, and is expressed through jazz and through the medium of improvisation. This is the highest form of being able to create music.” Speaking at the opening press conference of this year's Copenhagen Jazz Festival, that definition of jazz from the 80-year-old saxophone colossus Sonny Rollins seems as self-contained and eloquent as any other I've heard.

Certain Nordic countries are identified with particular forms of music. Norway and Finland are the home to various strands of metal. Sweden’s pop songwriters and producers are world-renowned, attracting the likes of Britney Spears to Scandinavia. Iceland homes individualists like Björk and Sigur Rõs. Denmark’s influential Mew and Efterklang capture mood like no one else. But you won’t find any of this on the new three-CD set Beginner's Guide to Scandinavia.

Bassist, vocalist and composer, Esperanza Spalding is one of the most exciting things to happen to jazz in recent memory. Born and raised on what she has called “the other side of the tracks” in Portland, Oregon, Spalding grew up in a single-parent home. Encouraged by her mother, she began playing violin at the age of five and gained a place in the Chamber Music Society of Oregon. By the time she left, 10 years later, she had risen to the position of concertmaster.

One of the great strengths of Manfred Eicher's ECM label is the way in which it has encouraged and documented many unlikely yet fruitful musical collaborations throughout its thousand-plus discography. First assembled for her season as artist-in-residence at Norway's Molde Jazz Festival in 2008, percussionist Marilyn Mazur's Celestial Circle quartet brings together stylists as individual as pianist John Taylor, bassist Anders Jormin and vocalist Josefine Cronholm (who makes her ECM debut here).
