Nine people are on stage. Male and female. None is singing. All are dancing. No instruments are being played. For a 20-minute, three-song segment of Swedish art-dance electro-tricksters The Knife’s London show the sound was of a live concert, but nothing else was. Then, for “Networking”, the stage emptied and the music continued. All that was left were lights beaming into the audience.

Born just a year apart in the 1950s and having both clocked up almost 40 years' work in their respective scenes, it's surprising that it's taken quite so long for fellow trailblazers Pat Metheny and John Zorn to work together. It's certainly been worth the wait, as this collection is a real barn-burner.

With a full-on commercial break in the middle of the programme and teary clips from the television show interspersed throughout, The Big Reunion live show really does play out like an extended episode of ITV2’s unlikely reality hit. Thankfully this means carrying over many of the things that made the TV show great, as well as giving late '90s/early '00s revivalists ample opportunity to purchase a £50 hoodie.

It was a carnival-like atmosphere and a packed house for the transatlantic trendsetters Major Lazer in Camden. Recent show reports suggested a more maximal and bombastic vibe from Diplo and his current sidekicks Jillionaire and Walshy Fire, but while the addition of these two stalwarts of the Caribbean music scene would suggest that the show was to be a faithful homage to the vibes of a Kingston dancehall or Trinidadian J’ouvert, this was sadly not the case.

Jazzfest has managed to succeed as a mainstream rock festival. The first weekend’s headliners on the main Acura Stage included John Mayer, Billy Joel and Dave Matthews, while this weekend promises Fleetwood Mac, Maroon 5 and The Black Keys. If the aforementioned suggest a festival devoted to AOR chart-topping US rock, then understand that the festival’s organisers allow the superstars to drag in suburban rock fans, thus underwriting the rich regional music flavours that dominate most of the other 11 stages.

Oh my goodness but that Mrs Carter knows how to entertain. Sparkles, glitter, flames, fireworks and costumes galore: The Mrs Carter Show had the lot and so much more. A tight eight-piece band, 10 dancers, three backing singers and extraordinary lighting effects - not to mention Beyoncé's honey voice, her sexy swagger and all-round bootyliciousness - made for a thrilling two hours in a cavernous space that she made feel almost intimate.

Continuing its voyage through Scandinavia’s music, theartsdesk opens the latest chapter in Norway with Still Life With Eggplant, the 16th album from Trondheim’s prolific, long-lived, occasionally challenging and always vital Motorpsycho.

There was a point about two-thirds of the way through last night's gig when someone lobbed something onto the stage in front of Mick Hucknall. It was not clear exactly what it was due to the sea of dancing mums in front of me, but my strong suspicion is that it was something made of lace and worn below the waist judging by Hucknall's bemused declaration: "That's Tom Jones's department."
