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.

Until a few weeks ago, I’d never heard of Maverick Sabre. Then I saw his weird potato-face looks and heard his utterly distinctive voice on Later... With Jools Holland, and was intrigued; thus I found myself last night at the Jazz Café in a sold-out crowd at his biggest London headlining gig, and I was impressed. He’s quite something.

Some theatre genres seem indestructible. One of these is the satirical city comedy, for which playwrights dip their pens in poison and spray their venom over the teeming mass of the shallow, the stupid and the successful. When they do this today, they inevitably recall all manner of past plays from Jacobean and Restoration times to Richard Brinsley Sheridan’s The School for Scandal, and beyond. In American Trade, a new play from the immensely talented American playwright Tarell Alvin McCraney, which opened last night, we revisit this familiar territory.

At one level the day of the single is gone - the 7-inch, the CD, the physical format - and yet, at another it's more relevant than ever. Sure, any track can now be downloaded from an album and hit the charts but singles, downloads - chosen representative songs - still give the best snapshot of what an artist is capable of. With this in mind, theartsdesk gleefully tucked into the latest batch of releases which includes Depeche Mode, Arctic Monkeys, pop, rave, folk and a whole lot more besides.

The last time I saw Atari Teenage Riot play was in a gig venue above a pub some time around 1999 and it was one of the most intense gigs I've ever experienced. Then-member Carl Crack – who would take his own life not long after – was clearly a man on the edge, and the entire group were acting wired, scared and weird. They made the most stupendous racket, and the well-over-capacity audience reacted by leaping about so violently that the building needed structural repairs afterwards. To be part of that seething crowd required commitment, passion and complete obliteration of ego – it was easy to see the power of the cult around ATR's leader, Alec Empire.

The question used to be: “Can white men rap?” A more apt variant today is, “Can white men in their middle forties with juvenile nicknames rap?” Mike D, Ad-Rock and MCA recorded Hot Sauce Committee Part Two in 2009, but then put the release on ice when MCA, aka Adam Yauch, was diagnosed with parotid gland cancer.

If, as the cliché goes, hardship begets soulfulness, then given her life story between her 2008 debut and this (Wikipedia can provide the details if you're feeling ghoulish), Jennifer Hudson should now be the new Aretha.

One of my most enjoyable gig-going experiences last year was seeing Mick Jones guesting with Gorillaz at the Roundhouse. The former Clash guitarist was clearly loving every minute of it. So much, in fact, that shortly afterwards he decided to reform his second-best band, Big Audio Dynamite, for a short UK tour, including the first of two London dates last night. But after two decades since this original line-up played together, the burning question was would this be a cynical, pension-funding slog, an arthritis-fuelled embarrassment, or something special?

The Sónar festival occupies a very special place in the New Music calendar – and is this year expanding outwards temporally and geographically, with new franchises in Tokyo and A Coruña, Galicia. Now into its 17th year, the parent festival in Barcelona serves as a vital meeting point for those of all stripes who refuse to acknowledge the polarisation of avant-garde and populism, or of club culture and the mainstream music industry. With 10 or more main stages and untold off-piste club events around the city, it would be impossible to condense even a single day and night of Sónar Barcelona into a standard gig-venue show, but that's what A Taste of Sónar tried to do last night.
