Harp glissandos, trilling flutes, the heft of a swinging brass section. Yes, last night's Jazz Voice once again kick-started the EFG London Jazz Festival in typically exuberant fashion. Arranged, scored and conducted by the indefatigable Guy Barker, its epoch-spanning celebration of jazz-related anniversaries, birthdays and milestones was hosted for the second time by Victoria Wood.

A little more than a year after the death of acclaimed jazz trumpeter and composer Abram Wilson, his former manager and widow Jennie Cashman Wilson has teamed up with EFG London Jazz Festival producers Serious to stage the only London tribute concert in memory of her husband.

In February 2010 I spoke to Lou Reed about his return to Metal Machine Music, a typically incongruous endeavour. Not content with touring his "difficult" 1973 suicide-song-cycle Berlin in 2008, he had decided to re-release his notorious 1975 "guitar symphony" and take his Metal Machine Trio on the road to perform entirely improvised instrumental music inspired by the spirit of the original album.

It's only the truly great albums that usher you into a sound-world that is entirely sui generis. And so it is with this second chapter of jazz sax player and composer Matana Roberts's Coin Coin project, a vast musical work-in-progress exploring themes of history, memory and ancestry. 

Think of the ingredients you look for in a great jazz record – inspired, exploratory improv, the complete reinvention of standards, ear-catching arrangements, sonorities you've never heard before – and this new big band recording from Mike Gibbs delivers them all. By the bucketload.

Squeaking toy pigs. Tea pots. Bicycle pumps. Yes, the dynamic Brazilian composer, arranger and multi-instrumentalist Hermeto Pascoal was back in town, making a rare appearance at Ronnie Scott's. Described by Miles Davis as “the most impressive musician in the world” - he first gained international recognition by playing on Miles's 1971 album Live-Evil - Pascoal's riotous polystylism incorporates jazz, rock and Brazilian music (MPB, bossa nova, chorinho, forro) to create what he calls musica universal or 'universal music'.

The great jazz singers are also the great storytellers. Last night, listening to Cassandra Wilson sing “Wichita Lineman”, that single, devastating couplet - "And I need you more than want you/And I want you for all time" - conjured up an individual's entire life story. Seamlessly traversing genres in fresh and creative ways, performing a set that juxtaposed Cesária Évora's “Angola” with a completely impromptu “A Foggy Day”, the Jackson, Mississippi vocalist, musician, songwriter and producer confirmed her own compelling storytelling gift.

The Meltdown Festival has always been a fascinating proposition, getting a living legend in their field to curate their own personal festival line-up, and present all of their idiosyncratic choices to London in the refined and retro-futuristic surroundings of the Royal Festival Hall.

Equal parts prodigiously talented musician, consistently funny comedian, auteur, theatre performer, free thinker and writer, Reggie Watts is nigh on impossible to pigeonhole. He is a hurricane of furious creativity operating completely in his own lane, hurtling full-speed towards Parts Unknown. Primarily known for his inimitable blend of improvisational music and comedy, each show he performs is completely original, never to be repeated.

The life of the stand-up is a balance, often precarious, between those stage moments when things seem to be going just right, and the ones which look like they're about to go very wrong. The hero of Tom Shkolnik's debut feature The Comedian, Ed (Edward Hogg), seems to be making decent progress with his club appearances, but when the chance of a new relationship comes along it puts the previously settled balance of his life right out of kilter.
