The 10-day London Jazz Festival, now in its 19th year, is a diverse and international festival that embraces the unapologetically commercial Jazz Voice, the outer reaches of (free) free improv and even Abram Wilson’s Jazz for Toddlers. Despite a line-up that’s both starry and distinguished there was no single name that might encapsulate the festival’s rainbow palette. You can get a taste of its breadth from the three giants competing for our attention on the final night: Brazilian pioneer Hermeto Pascoal, guitarist Bill Frisell and free-jazz pioneer Ornette Coleman. 

It’s nine days into the 10-day London Jazz Festival, and highlights so far include the double bill of saxophonists Steve Williamson and Steve Coleman, and the UK’s own Empirical supporting veterans Archie Shepp and Joachim Kuhn (the former a mellowed African-American firebrand, the latter a German pianist with all the wild intensity of Klaus Kinski in a Beethoven biopic). Contemporary crooner Gregory Porter, who played the "Jazz on 3" launch at Ronnie Scott’s, didn't do much for me, but it seems already to have been written that he is THE FUTURE OF JAZZ and it might just come to pass.

There aren't too many pianists who excite jazz aficionados and hip-hop fans in equal measure. But then no other artist has been inspired equally by hip-hop beats on the one hand and Thelonious Monk on the other. And while it appears increasingly that jazz artists are refusing to be straitjacketed by genre convention, US pianist Robert Glasper is perhaps the prime example of this blurring at the edges.

This show was memorable almost as much for the audience as it was for the music. The Roundhouse was perhaps two-thirds full for a show that The Low Anthem’s singer Ben Knox Miller said was “the biggest gig of their career” (adding: “And I’ve never called it a ‘career’ before”), but those who were there had clearly come to see the band rather than catch up on gossip, because the audience’s attention was absolute, their silence total; I can scarcely recall a gig where the crowd’s concentration was so complete.

Funkier than a James Brown bridge, the mighty Soul Rebels Brass Band swung back into town last night and flattened all before them. Possessing that rare combination of serious chops, impeccable stagecraft and down-home soul, they confirmed their position as one of the most explosive live acts on the scene. From the very opening bars of Stevie Wonder's “Living for the City”, taken from their current Rounder album Unlock Your Mind, the Soul Rebels had the entire QEH off their seats.

“Whose idea was it to do the gig in this shithole?” asks Captain Sensible towards the end of the night. He’s right. The East Wing is truly an atmosphere-free venue, a carpeted, low-ceilinged conference room that’s part of the much larger Brighton Centre complex. It’s easy to imagine it filled with municipal administrators milling about, the stink of coffee and the rustle of paperwork. Instead, it’s packed to the gills with men and women, mostly in their late forties and early fifties, mostly clad in black, lots of leather and badges.

Over the past decade I’ve always been more an admirer than a fan of Susheela Raman, wanting to like her music more than I did. But her latest album Vel has changed all that. It’s an uncompromisingly dark and powerful statement that makes no concessions to what one might call “world music” tastefulness. It still incorporates some of the languid sensuality and meditative mood associated with previous works, but incorporates a harder, at times even angrier edge which makes it wholly unique.

It would be difficult to imagine a more impressive curtain-raiser to the London Jazz Festival than Jazz Voice, and this year's vintage was the finest yet. One sensed from the very opening bars of Gregory Porter and Ian Shaw's a cappella duet, “Feelin' Good”, that something remarkable was about to unfold, and so it proved.

She grew up in Norway, lives in Sweden and has been recording since 2003. Her new album, It All Starts with One, is her most assured, her most vital. But Ane Brun’s recent work with Peter Gabriel has attracted attention outside Scandinavia. Her vocal contribution to his remake of “Don’t Give Up” claimed it as her own. Last night erased Gabriel from her CV. This fabulous show was a new beginning.

Some successful rock stars accumulate wives, others accumulate houses, cars or drug habits. Damon Albarn seems to accumulate bands. As well as his on-off relationship with Blur, there is the semi-regular Gorillaz. And he has  been seeing even more musicians on the side, too. He recently appeared at the Barbican alongside the Red Hot Chili Pepper’s Flea (must have been a seven year itch?) and last night he rekindled an old flame, reconvening The Good, The Bad & The Queen for a one-off Greenpeace benefit.
