CD: Africa Hitech - 93 Million Miles

Bravura electronica genre-collision lets the machines sing

This is, not to put too fine a point on it, a masterpiece – but it could easily have been a bloody mess.

Syriana, Purcell Room

“Oh, there you are!” Some but not all of Syriana finally locate the photographer

Cold War chill and Arabic heat from this multicultural collective

As someone brought up on the concise innocent perfection of the pop single, I have to confess I’m a bit of a hard sell when it comes to sprawling instrumentals. They feel like unfinished songs to me; empty landscapes that need figures in them to create context, narrative, or just a focal point to give meaning to the whole. But there have been a few primarily instrumental acts over the years that have convinced me, and the multicultural five-piece Syriana have now joined their ranks.

CD: African Head Charge - Voodoo of the Godsent

A worthwhile addition to the band's spaced-out oeuvre

For 30 years African Head Charge have been ploughing their unique sonic furrow, wandering hazy-dazed around the outer borders of experimental dub and super-mellow sounds. When they first appeared in 1981 on Adrian Sherwood's groundbreaking On-U Sound label there was no equivalent band to compare them to, except some of Brian Eno's global magpie studio excursions, notably My Life in the Bush of Ghosts with David Byrne which provided them with a sonic template.

CD: Kode9 & The Spaceape - Black Sun

Kode9 & The Spaceape's 'Black Sun': 'An endlessly listenable and quite timeless album'

Can deep electronica and politicised dub poetry escape worthiness?

There's something about this album that feels as if it's already existed for a long time. Full of post-apocalyptic images of smoke, dust, decay and weakness, and themes of struggling individuals and implacable political forces, it thematically fits with the works of a long line of acts who positioned themselves against the fear of nuclear armageddon and the seemingly immovable Conservative government in the 1980s. Its mix of Caribbean-influenced soundsystem culture and dub poetry with an edgy alternative experimentalism, too, harks back to the post-punk genre collision of Dennis Bovell, On-U Sound, Renegade Soundwave and the like, 25 or more years ago.

Reggae Britannia/ Rocksteady: The Roots of Reggae, BBC Four

From Trenchtown to Camden Town with the Beeb's Reggae Britannia season

BBC Four's Britannia series keeps it simple - it tells the story in a straight line, illustrates it with as much archive material as the budget will allow, and interviews as many key protagonists as it can find. If the subject is strong enough, you'll get a good film out of it.

Save The 100 Club!

Stars flock to rescue historic venue

Musical luminaries including Mick Jagger, Paul Weller, Ray Davies and Liam Gallagher are lending their support to a campaign to save The 100 Club, the historic music venue in London’s Oxford Street. Soaring business rates of £4000 a month and an annual rental bill of £166,000 have driven the club to the brink of bankruptcy, and unless the savethe100club campaign proves successful, it faces closure by Christmas.

Dub Colossus, Bloomsbury Ballroom

A triumphant return for this British and Ethiopian collective

I’d not been to the Bloomsbury Ballroom before, but over the past five years or so the likes of Amy Winehouse and Martha Reeves have played this plush Art Deco space. Somewhat disconcertingly, apart from the stage, the rest of the hall was in virtual darkness which suited Dub Colossus perfectly: this intriguing collective of British and Ethiopian musicians are purveyors of intense, atmospheric dance music who actually benefited from this dramatic lack of lighting which made the stage appear to glow like a coal furnace.

Magnetic Man, Heaven

Magnetic Man's LED cage

Dubstep trio fill the generational gap

Rave music, in its many ever-mutating forms, is now more than a generation into its existence. Many, possibly most, of the crowd pushing into Heaven, under Charing Cross station, weren't even born when acid house fully hit the UK in 1988, but none of them are here for some retro experience. It's hard, as a superannuated lover of electronic beats, not to feel cultural vertigo at the fact that what once felt like the most impossibly inhuman of sounds has now become so ubiquitous and so established as to be a kind of folk music. But there it is, as established as the blues or punk rock, and as woven into the fabric of our lives, yet still mutating and still throwing up fresh variants such as the dubstep which Magnetic Man play.

RIP Ari Up

Ari Up in 2006

Ari Up, frontwoman of The Slits from the age of 14, died yesterday aged 48 after a long illness, it was announced by her stepfather, John Lydon of the Sex Pistols. The brilliant and confrontational female-fronted Slits were one of the finest examples of the punk era's DIY creativity, and also one of punk's most successful engagements with reggae. Ari Up never stopped being a fervent supporter of reggae culture in all its forms: after The Slits she formed New Age Steppers with legendary British producer Adrian Sherwood, and for many years she lived in Kingston, Jamaica where she was a keen participant in the local dancehall scene under the name Medusa.

Jonathan Richman, Amersham Arms

The rock'n'roll one-off brings that summer feeling to New Cross

In 1985 I travelled to Madrid to interview Jonathan Richman. Two questions into our perfectly amicable chat, proceedings assumed pear-shaped proportions. The eccentric musician behind the proto-punk hit "Roadrunner" announced that he did not want to speak any more so that he could preserve his voice for the gig that night. The rest of the interview was conducted by pen on a piece of scrap cardboard.
