There's a whole world of music out there that floats in the zone somewhere between jazz, club music, sound art, contemporary classical and meditative new age background sound – so much of it that it all too easily blurs together. But there are artists who can make something more, and when you stumble on something truly individualistic like this album it shines out like a beacon in the fog.

Just how good is Gregory Porter's Be Good? Put it this way, over the course of a single song Porter can deliver an emotional payload which some jazz wannabes fail to achieve over an entire career. Combining the tropes of jazz and soul in an entirely seamless way, all wrapped up in a fabulously rich baritone, it's an album to relish from start to finish. The oft-made comparisons with the likes of greats such as Nat King Cole and Donny Hathaway appear far from fanciful.

Naturally 7 represent the point where close-harmony singing, beatboxing and spookily accurate instrumental imitation meet. The US septet call it "vocal play" - the voice as instrument - and last night they sent dopamine levels soaring in the Barbican. The group conveys the beat-driven swagger of hip hop, the freewheeling improv of jazz and the trenchant emotion of soul, often within the confines of a single song. Their arrangements, courtesy of MD Roger Thomas, possess such textural imagination and technical finesse that they're able to traverse genres seemingly without artifice.

Soweto Kinch's set last night as part of the eXplorations mini-series featured gluttony, envy and a host of other vices. No, not A Life in the Day of an Investment Banker, but a tantalising glimpse of Kinch's take on the Seven Deadly Sins.

Every year at the Edinburgh Fringe there's a sleeper hit, or a show that promises little on paper but delivers big time in the flesh, and this year's unexpected success was Set List, a kind of improv for stand-ups, which has also been called “comedy without a net” or “like flying without wings”. Only the bravest comics attempted it, and now the show's producers are putting it on in London for a few performances so more people can see whether those descriptions are accurate, or simply prove that comics like a bit of hyperbole.

Toumani Diabaté is the world’s greatest and best-known kora player. Plugged in deep to a musical tradition that goes back over seven centuries, this griot or jali takes his custodial role very seriously, but he is also an adventurer who has stretched the repertoire of his ancient strings by listening avidly to music from an astonishingly wide range of sources.

Spoiler alert: this CD contains grooves that will bring out your inner air guitarist. From the album's lead-off song, “Tenderly”, whose sumptuous voicings lesser artists can only fantasise about, to its towering sign-off, “Fingerlero”, George Benson's 24-carat gift for free-flowing improv remains a thing of wonder. “Fingerlero” also features one of the most recognisable and heart-stirring sounds in jazz: Benson scatting in perfect unison with his deftly picked guitar lines. He makes you wait, but it's so worth it.

This Edition Records debut from pianist Andrew McCormack and saxophonist Jason Yarde is a powerful marriage of brilliant musicianship and composition of the first rank. While this is only their second release in the duo format, a follow-up to the 2009 album My Duo, their attention to the smallest detail of phrasing and dynamic has been steadily honed since the days of playing together in seminal groups J-Life and Tomorrow's Warriors, dating back to the 1990s.

While the physical and mechanical elements of its production are common to all, the sound of a person's voice is as individual as a fingerprint. Launching her Brazilian-themed solo album Lágrimas de um pássaro (Tears of a Bird) in the intimate surroundings of Soho's Pizza Express Jazz Club, Heidi Vogel's extraordinarily rich and complex vocal timbre proved capable of completely seducing the senses.

Luke Haines, Cabaret Voltaire ****

If the cards had fallen differently Luke Haines might have been as big as Blur. As frontman of The Auteurs he was briefly tipped for Britpop greatness, so it is no surprise that he likes the idea of alternative histories. This special show, The North Sea Scrolls, was all about them, as Haines, former Microdisney linchpin Cathal Coughlan, writer Andrew Mueller and cellist Audrey Riley mixed spoken word with punchy lo-fi melodies.
