Where’s the African car? Seun Kuti wanted to know. There are German cars, Chinese cars (he grimaced) even Brazilian cars. At least, anyway, there is “original African music”, not traditional but something new. Actually, not entirely new, as some of the music and some of his band, Egypt 80, were that of his father, that visionary genius, subversive and sex maniac Fela.

Joker, aka 22 year old Bristolian Liam McLean, is one of the most individual talents of the dubstep/grime generation. His long run of dancefloor-directed single releases, some originally recorded when he was in his early teens, showed natural gifts for finding the funk in the sparsest rhythms and for frazzlingly catchy melodic synth riffs which meant his productions leapt out of DJ sets wherever and whenever they were played. Now, following a quiet 18 months, his debut album shows that he's not content to rest on his laurels.

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.

There’s more than one way to reinterpret or simply embrace the extraordinary wealth of Ethiopian music that Francis Falceto has given us with the still growing Ethiopiques CD series of 1970s Ethio-jazz (as the style has been inadequately labelled). For example, Dub Colossus were seduced by the dissimulating aspect of the music that they felt it shared with dub reggae. And the Heliocentrics embraced its “otherness” over which they imposed their own art-school sensibility. Somewhere between these two approaches comes Switzerland’s Imperial Tiger Orchestra.

I'm not quite sure why Anthony Kiedis bothered to put on his multicoloured frock coat. It certainly wasn't to keep warm. The atmosphere in Koko was positively volcanic even before the Red Hot Chili Peppers appeared on stage at this exclusive Radio 1 showcase. Highlights are due to be broadcast during Zane Lowe's show on 12 September from 7pm to 9pm, but a radio airing will convey only a miniscule fraction of the zip of this age-defying band.

In 1989 when Lenny Kravitz released his debut Let Love Rule people complained that he had failed to quite master the Sixties influences that cut through it. They were wrong. That year it made Kravitz the most exciting black/white crossover artist since Prince. Since then, his path has been mainly a little more straightforward - maybe a little retro, but still consistently stirring. However with Black and White America Kravitz has again thumbed back through his Black-American songbook to find new styles with which to score his treatise on 21st-century race relations. Is it as good as Let Love Rule? Simple answer, no.

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.

Little Rock, the state capital of Arkansas, usually comes to mind in association with hometown boy Bill Clinton. Soul and funk fans, however, aren’t fussed with the sax-playing former governor and president and fixate on the city’s True Soul label, the home of a raft of rare and sought-after sides. Two volumes compiling the imprint have just been issued and include previously unissued tracks. The harmony-driven soul, Southern grooves and tight funk make a case for True Soul being an essential component of soul USA.

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.
