Born in Los Angeles, raised by his mother in Bakersfield, and now living in the Bedford-Stuyvesant area of Brooklyn, Gregory Porter's resonant baritone is one of music's wonders. Porter's Grammy-nominated debut album, Water, has earned him praise from critics and fellow artists alike. Released in the UK in April this year to coincide with his appearance on Later... With Jools Holland, Water leapt to Number One in both the UK's iTunes and Amazon charts.

This is a strangely kaleidoscopic approach to documentary. A selection of recently unearthed footage and interviews which shows the Black Power movement in the USA through the eyes of idealistic Swedish film-makers, now re-edited and framed with the voices and music of both modern and veteran black radical cultural figures, it provides a disorienting, shifting set of superimposed viewpoints of a period in which in any case change seemed to be the only certainty.

Justin Adams is considered to be one of the UK’s most original guitarists and record producers and is an extremely versatile collaborator. He was brought up in the Middle East - his father was a British diplomat in Jordan and Egypt - and his music is very strongly influenced by his early exposure to Arab culture, in addition to African music, blues, dub and psychedelia. 

Pauline Black, the lead singer of 2-Tone band The Selecter, was born in 1953 to an Anglo-Jewish mother and Nigerian father and was adopted as a baby by a white working-class couple from Essex, who refused to acknowledge she was black. However, by adolescence she was determined to define herself as society saw her and changed her surname to Black by deed poll when she was in her twenties.

At the start of September, the fourth Outlook Festival takes place in a 19th-century fort on the Croatian coast. Already this festival has become a vital point in the calendar for those involved with dubstep, grime and other UK underground scenes – not only a jolly in the sun (“dubstep's Ibiza”), but the one time in the year when everyone involved takes a break from international touring and comes together in the same place, a time to compare notes and take stock of the progress.

It's not often you can call pop music revolutionary, but this record is - in more ways than one. Bringing together techniques of engagement that have been honed by Radiohead, Lady Gaga, Lil Wayne and... um... Justin Bieber, the 21-year-old Berkley, California rapper Lil B appears to be on the verge of becoming the first bona fide internet-birthed superstar. I'm Gay (I'm Happy) appeared on iTunes yesterday, announced with a single tweet, with no prior warning whatsoever bar an announcement of its provocative title a couple of months back. It has seemingly no standard record company support behind it, yet it is instantly huge news.

Well, there's a nice surprise. Jill Scott was feared lost to music industry machinations, more likely to succeed in her acting career than make a fourth album (she's probably best known now to mainstream British audiences as Mma Ramotswe in The No 1 Ladies' Detective Agency TV series). But it seems a four-year musical hiatus and change of label has done her the power of good, as this is the Philadelphia singer and spoken-word artist's best album since her debut Who is Jill Scott?

This month sees an audacious attempt to showcase British dancehall music, when the Cargo venue in Shoreditch hosts the multi-artist revue Showtime!. The Heatwave collective have brought together vocalists from various UK underground scenes, linked by a strong influence from the high-energy Jamaican sounds of the past 30 or so years. While many of the artists involved have found success in crossover scenes like rave, jungle, grime and garage, the appeal of dancehall itself (also known by the overlapping terms bashment and ragga) has traditionally been restricted to predominantly black audiences.

To the relief of many an international batsman, there has never been anything to rival the stupendous West Indies teams which bestrode Planet Cricket with intimidating ferocity from the late Seventies into the Nineties. Fire in Babylon is the story of the side that Clive Lloyd built, and the way it became a formidable socio-political force in the Caribbean as well as a sporting global superpower.

The opening images have mighty symbolic heft. A boy dashing across a blasted wintry field compels a flock of birds to take to the air, hundreds if not thousands of them blackening sky and screen, squawking and flapping in cacophonous unison. Cut to a freight train, truck after truck, thundering under clouds across the barren land. Cut to two plastic deer parked outside a wooden prefab. By the end of this brief montage it is clear we are being invited into a world from which, for its tragic human inhabitants at least, there is no chance of escape.
