It's been a while since the pop/punk and post/pre-Richey comparisons have been made. Ironic considering how seemlessly the Manics slip between modes these days. Today theartsdesk brings you an exclusive preview of the live, power-popping video of "Hazleton Avenue", due for release next Monday to coincide with their live digital EP, Some Kind of Nothingness (available on iTunes).

As New York gypsy punk live sensation Gogol Bordello tear into another Balkan rebel hoedown in front of a capacity Brighton crowd I'm reminded of an old Stones lyric, Jagger and Richards's 1971 classic "Dead Flowers": "When you're sitting there in your silk upholstered chair/ Talking to some rich folks that you know/ Well, I hope you won't see me in my ragged company/ You know I could never be alone". Gogol Bordello epitomise the rock'n'roll "ragged company", the scruffy outsiders.

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.

Bellowhead are 21st-century genre-busters: punk music-hall madness born out of British folk, seasoned with a zeitgeist-friendly dose of multicultural spice. Sounds gimmicky? Well, not at all, as Bellowhead’s greatest quality, apart from being an outstandingly enjoyable live act, comes from the way they ride their eclecticism with brio and intelligence, inventing as they go a new folk music for our times.

Unlikely cool. It’s what unites LCD Soundsystem and Hot Chip. They’re the geeks and outsiders who made it to being hip on the dancefloor. These improbable, subversive electro-pop heroes have united this autumn for what for fans has been a dream double-headline tour. Both bands have had albums out this year and both albums have been well received. But for James Murphy the rumours are that this may be the last tour he does as LCD Soundsystem. And last night he sure was playing as if saying a long goodbye to the ones he’d loved.

Is it a bird? Is it a plane? Is it an amphetamine-fuelled chicken on rollers? No, it’s the one-time guitarist for Dr Feelgood (during the only period that matters) still doing the moves that made him the main reason to see the band in the mid-1970s. Now bald-headed and bushy-browed but still delivering those electrically charged stares (which he learnt to do during a brief stint as a schoolteacher), he had the air of a benevolent dictator last night as he surveyed the Academy’s crowd for would-be assassins to mock-machine-gun with his trusty Stratocaster.

It is not easy to kickstart a fresh musical career after you've been in a painfully fashionable – and intermittently brilliant – band. It is even harder when this is your second bash at starting out again. And harder still when a couple of months ago you trousered enough money to keep you in leather jackets for a lifetime by briefly reforming that original band for a pair of festival cameos. Yet last night erstwhile Libertine and ex-Dirty Pretty Thing Carl Barât did enough to suggest that, if he digs his heels in, his personal rock drama might have a memorable third act yet.

“It’s not often you get a global superstar down at the Elephant and Castle,” marvelled a local who spent the evening dancing like a dervish to the infectious music of Manu Chao, who had breezed into London for a rare show last night off the back of a short tour of Japan and the West Coast of America. The first person I saw as an usher was Colombian philosopher Oscar Guardiola-Rivera whose book What if Latin America Ruled the World? suggests - among many other things - that the US is becoming the next Latin American country. Like the others he was wearing a Colombiage T-shirt - the organisation for which this was a benefit.

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.
