Ambrose Akinmusire is the new jazz sensation, the messiah of the post-bop trumpet. With his hyper-talented and youthful quintet, the 29-year-old Californian delivered a set in Bristol that rang all the changes from the soft and lyrical to high-energy heat.

The dazzling Cuban pianist Roberto Fonseca delighted a packed Barbican last night – but part of the fun was seeing him negotiate the balance between more soulful, minimal playing and sheer technically brilliant extravagance. Is he more an heir to Chucho Valdez, the consummate sophisticated Havana Jazzer, or to Ruben Gonzalez, the more lyrical pianist of the Buena Vista Social Club, into whose shoes he had the tricky task of stepping for their live tours? 

To dubstep or not to dubstep, that was the question perplexing the nearly 5000 metalheads jammed into the Brixton Academy to see Korn.

The X Factor has made it far easier for fans to connect with artists from the get-go - as far as the viewer is concerned, the life story of each auditionee starts at episode one. Following JLS from that first audition to a third sold-out arena tour in the space of just four years has instilled a sense of pride in even the youngest of fans. 

I don't much like aspirational music-making. I like my classical classical and my pop pop. Give me Boulez over Bernstein, Britney over Radiohead, any day. Having said that, I'd heard a piece by Jonny Greenwood at Reverb last month that had gone some way to winning me over. For a brief moment, Greenwood dropped the avant-garde pose that he's adopted for most of his other classical compositions and indulged in a bit of tender-hearted Romanticism that was nothing if not charming. This kind of honesty was not much in evidence in his team up with Penderecki last night at the Barbican. 

It’s sometimes difficult to imagine that a new pop star can ever live up to even the most optimistic fan’s expectations. Spiralling hype and contagious squeals over mp3s are one thing, but with the subject standing before them to perform a full live set it’s all too often a different story - the cloak is removed and hark, there’s a human being behind it. A human being who talks, sings and performs songs we’ve never heard before! How are we supposed to love something clothed in properties from the ether?

The Civil Wars are one of those bands rendered suddenly white hot in the UK by a classy performance on Later with Jools Holland. They’re a photogenic country-ish acoustic singer-songwriter pairing whose style is just un-country enough to fit neatly alongside James Morrison on Home Counties i-players, but whose very, very faint tint of Deep South gothic also has the hipsters intrigued. They have sold out the Shepherds Bush Empire tonight and arrive on stage to enthused applause and yells of appreciation.

I had a terrible fright last week. While listening to BBC London DJ Robert Elms introduce a track from the new Paul Weller album, Sonik Kicks. What I heard sounded remarkably like Oasis. It seemed that the man who once influenced Noel Gallagher was now so bereft of ideas he was reduced to ripping off Noel Gallagher. To my relief Robert Elms followed the track with an apology. He had pressed the wrong button and had played a Noel Gallagher track by mistake.

If you've got enough hair to make it stand up at 53, why not flaunt it?

In the age of Mumford & Sons we should recall that half a century ago, folk music wasn’t so much acoustic pop as agitprop, staunch leftwing propaganda. Singers such as Ewan MacColl and Peggy Seeger toured songs rife with witty, angry social discontent, incidentally setting in place the UK’s early gig and festival circuit.

Bringing together the most talented choirs, vocalists and musicians from across London and the UK, iGospel's two-day Sing Inspiration! Festival came to a close in spectacular fashion. Lurine Cato opened the concluding "Gospel & Soul" concert, showcasing her impressive five-octave range on “You Revive Me”, the first single from her forthcoming debut album. With one, ever higher, key change after another, Cato's deluxe pipes made some better-known pop singers sound like common-or-garden pub belters.
