“It’s cultural imperialism,” a middle-aged gentleman felt compelled to say to me, presumably because I was the bloke with the notebook. “Then all pop music is cultural imperialism,” is what I should have fired back at him, had I not been so immersed in the transcendental racket of tussling brass and distorted guitars that had almost made him inaudible. But instead I took the scenic route of pointing out that this legend of 1970s Ethiopian jazz would hardly have spent the last seven years playing with these white Dutch musicians if he had felt he was being exploited.

Some critics have lazily compared Baloji to Somali rapper K’nann: both are African rappers who had lucky childhood escapes from countries about to descend into war and chaos, but beyond that they seem to have quite different approaches to what they do. K’naan is as much a pop musician and poet as he is a hip-hop artist, firmly concentrating on melody, song structure and hooks. Whereas Baloji, at least on the evidence of this album, seems to want to engage more with roots music while finding ways for his rhymes to fit in with already established musical idioms.

I’m stood in the dusk in front of the tomb of Sheikh Hamid al-Nil as the sun sets on Khartoum, reddening in the exhaust-filled air as it deflates over a receding jumble of low-rise blocks spreading down the banks of the Nile and out towards Tuti Island, where the waters of the Blue and White Nile meet. This is no quaint, picturesque view, though you do feel you're in some ancient theatre of humanity when you land in Khartoum.

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.

When I first saw this Malian singer-songwriter a few months ago at a showcase gig in a grimly carpeted basement bar in Clerkenwell it was hard to imagine a less appropriate space for such a regally beautiful woman to be found in. Yet within a couple of mantra-like songs she had conjured her own ambience, causing the tardy space to become irrelevant, at least until the last notes died away.

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 love the fact that under the “genre” tab on their Facebook page, Orchestre National de Barbès have opted for “Other” from the dropdown menu. Obviously in Facebookland “Other” simply means not rock, soul, hi-hop, jazz, reggae, classical etc. However, in a metaphysical/philosophical sense “Other” can mean that which is alien, different or exotic. But what tickled me is that the music of this Parisian-based, largely Algerian band actually embraces just about all the Facebook categories they could have clicked on, even if none of them fully sums up the multilayered din they create.
