After his spectacular performance at the Brit Awards, the stage running amok with a dancing jury, shimmying riot police and balletic convicts, I wasn't sure what to expect from a Plan B show. Perhaps a theatrical experience somewhere between Rick Wakeman's infamous 1975 King Arthur on Ice extravaganza and the Ray Winstone borstal flick Scum? But, no, the newly minted Brit-hop soul star adheres to a traditional band format, albeit sharp-suited and backed by two feisty gospel-belter ladies.

It seems to me that Esben and the Witch would like to perform in absolute darkness. Or perhaps in silhouette behind a screen like an oriental shadowplay. Such a theatrical device might even suit their dark, menacing music. Instead, two of the three band members have to make do with a curtain of hair between themselves and the audience. Young and shy, they deliver their moody, occasionally explosive music with low-key confidence and, in fact, their slight awkwardness in front of a crowd only enhances the edginess of the atmospherics.

Revisiting Brighton Rock was bound to cause an uproar. A couple of weeks ago, The Daily Telegraph’s Simon Heffer launched a ferocious assault on Rowan Joffe’s new screen version of Graham Greene's novel, while admitting he hadn’t seen it. Mind you, he had read some hostile comments on the internet. “Well ought to have been left alone,” he decreed.

The last album from Brighton’s The Go! Team, 2007’s Proof of Youth, followed the template set by Thunder, Lightning, Strike, their 2004 debut. AD-HD sample-driven songs met Northern soul and hip hop with call-response vocals and melodies that could have graced any Sixties girl group. All at 80 miles an hour with xylophones and brass. Third time round, Go! Team mainman Ian Parton has stretched out without sacrificing what was great in the first place. Rolling Blackouts is The Go! Team’s best album so far.

Here, we present the exclusive first showing of a new video by the Brighton/London band Belleruche. This clip for “Fuzz Face” is highly arresting, an ingenious and slightly disturbing collision of hi and low-tech, made using thousands of photocopies, and its indicative of a band who are taking some very interesting ideas into the mainstream. But more importantly from theartsdesk's point of view, Belleruche's increasing profile is indicative of a broader cultural shift in the music world.

The great music writer Nick Tosches put me onto James Luther Dickinson. In Where Dead Voices Gather, his self-indulgent but fascinating book about the obscure early-20th-century minstrel performer Emmett Miller, Tosches kept touching on Dickinson, a Memphis musician and occasional Rolling Stones sidesman (he played piano on "Wild Horses").

Tired of the slick, pastiche world of the post-Lock, Stock... British crime movie? Then Down Terrace may be the address for you. Director Ben Wheatley’s micro-budget, naturalistic debut details the paranoid decline of a drug-dealing family in the back end of Brighton. They’re the Royle family with access to hand guns - a deadly and funny combination.

If you thought Chamber Pop was dead, think again. The Divine Comedy are back with a new album, Rufus Wainwright is playing Meltdown, and The Leisure Society are gradually building up a cabinet of awards. The genre may sometimes come over as the musical equivalent of David Mitchell in Lawrence Llewellyn-Bowen’s clothes; but over-educated young men, it would seem, will not be easily be distracted from expressing their ironic observations.
