Rooted in the New Orleans brass band tradition, but updating it for the 21st century with elements of funk, R&B, hip hop, reggae and half-sung, half-rapped lyrics, this disc will blow clean out of the water any preconceptions you might have of what a brass band sounds like.

Better him than Black Eyed Peas, eh? Will.I.Am never came up with a line like, "Just sittin' here chillin' in the Batcave/ Whilst listening to Nick Cave/ Last night was a sick rave". In fact, that lively sliver of channel-hopping doggerel pretty much sums up Example. His lyricism has both cheese and cheek but is undeniably compulsive, laced with bubblegum hedonism. As for the music backing him, it's 21st-century electronic homogeny run riot - bangin' Euro-trance, dubstep, drum and bass, a dash of hip hop, soft-rock tropes, no shortage of melodies and big breakdowns.

At the start of September, the fourth Outlook Festival takes place in a 19th-century fort on the Croatian coast. Already this festival has become a vital point in the calendar for those involved with dubstep, grime and other UK underground scenes – not only a jolly in the sun (“dubstep's Ibiza”), but the one time in the year when everyone involved takes a break from international touring and comes together in the same place, a time to compare notes and take stock of the progress.

I'm not claiming some major prescience or insight here. I am as guilty as anyone of dipping into the music of the sink estates for a small dose of frisson then returning to art and music that confirm my own worldview. But maybe, just maybe, if we had all paid more attention to what was being said by young British men and women from those estates over the last decade, the events of the past few days might not have come as such a horrific surprise.

The musical identity of Midlands town Stourbridge is largely defined by Ned's Atomic Dustbin, Pop Will Eat Itself and The Wonder Stuff, a trio that charted with varying degrees of wackiness in the late Eighties to mid-Nineties. The Voluntary Butler Scheme, the recording identity of fellow Stourbridgian Rob Jones, shares their leaning towards wackiness, but it’s more surreal, less surface. He’s also way more interesting musically. Second album The Grandad Galaxy is a musical rummage through a jumble-sale mind.

Bassist, vocalist and composer, Esperanza Spalding is one of the most exciting things to happen to jazz in recent memory. Born and raised on what she has called “the other side of the tracks” in Portland, Oregon, Spalding grew up in a single-parent home. Encouraged by her mother, she began playing violin at the age of five and gained a place in the Chamber Music Society of Oregon. By the time she left, 10 years later, she had risen to the position of concertmaster.

It's not often you can call pop music revolutionary, but this record is - in more ways than one. Bringing together techniques of engagement that have been honed by Radiohead, Lady Gaga, Lil Wayne and... um... Justin Bieber, the 21-year-old Berkley, California rapper Lil B appears to be on the verge of becoming the first bona fide internet-birthed superstar. I'm Gay (I'm Happy) appeared on iTunes yesterday, announced with a single tweet, with no prior warning whatsoever bar an announcement of its provocative title a couple of months back. It has seemingly no standard record company support behind it, yet it is instantly huge news.

Well, there's a nice surprise. Jill Scott was feared lost to music industry machinations, more likely to succeed in her acting career than make a fourth album (she's probably best known now to mainstream British audiences as Mma Ramotswe in The No 1 Ladies' Detective Agency TV series). But it seems a four-year musical hiatus and change of label has done her the power of good, as this is the Philadelphia singer and spoken-word artist's best album since her debut Who is Jill Scott?

Certainly a good cross-section of people were in attendance for the first day of Sónar.
