Mick Jagger is heading up a band named SuperHeavy. Also in on the project are Joss Stone, AR Rahman (composer of the Slumdog Millionaire soundtrack), Dave Stewart (the former Eurythmic) and Damian Marley. It seems outlandish and the product of an overheated PR person’s imagination, but many things in life can be both. Yet, this is real, not an April Fool-type joke.

The Motown label will forever be identified with its Detroit birthplace, even though it had a Los Angeles office in the Sixties. The shift west was completed in 1972 when founder Berry Gordy Jr moved the whole concern to California. Before that though, in 1971, Gordy had launched subsidiary imprint Mowest to ostensibly showcase Los Angeles acts and as a test run for the California move. This gold-chip compilation shows Mowest is worth remembering. Motown's Mowest Story 1971-1973: Our Lives are Shaped by What we Love is the first comp to dig into this all but lost imprint.

This is where the delirium kicks in. Tired but happy, the attendees started the third day of Sónar festival slightly boggled by how to pick and choose from the strange delights on offer. Saturday was when the true musical variety of the festival was displayed: straight-up hip hop to eye-popping South African tribal dance displays, balmy ambient revivalism to apocalyptic techno, heartbroken electronica to deranged prog rock: it was all on offer...

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

The house music of Chicago, led by producers and DJs, has long had a tendency to feature the greatest vocals of any genre yet not make stars of its singers. And for most of his working life, Darryl Pandy, who died yesterday aged 48, was not the star his huge presence and elemental, gospel-schooled voice warranted – instead working the club circuit and soul revival shows, and featuring on dance tracks scattered across dozens of 12" singles on many labels worldwide.

Although record producer Martin Rushent was firmly identified with the punk and post-punk eras, the biggest records he had worked on before then were those of Shirley Bassey. His production of The Human League’s epoch-defining Dare changed that.

This month sees an audacious attempt to showcase British dancehall music, when the Cargo venue in Shoreditch hosts the multi-artist revue Showtime!. The Heatwave collective have brought together vocalists from various UK underground scenes, linked by a strong influence from the high-energy Jamaican sounds of the past 30 or so years. While many of the artists involved have found success in crossover scenes like rave, jungle, grime and garage, the appeal of dancehall itself (also known by the overlapping terms bashment and ragga) has traditionally been restricted to predominantly black audiences.

Next Tuesday, 31 May, will be a day of difficult choices for fans of New York’s Sonic Youth. London is hosting three separate shows by band members and associates. That evening their mainstay guitarist, Thurston Moore, plays the Union Chapel. SY’s drummer, Steve Shelley, is at The Borderline, guesting with Chicago’s Disappears. And Half Japanese, who both Shelley and Moore have collaborated with, are headlining at The Scala.

Private music patrons aim to raise £2 million to fund 400 scholarships for London children with a talent for music. The aim is to give steady four-year support for disadvantaged children to have Saturday lessons, individual coaching and group tuition to learn a musical instrument. Alongside the scholarships, there is to be a "partnership" scheme whereby professional musicians go into schools to work on music with up to 10,000 schoolchildren.

In the ravages of the recent arts cuts, and debates over the winners and losers, one estimable organisation tended to be overlooked in the coverage – the Asian Music Circuit, who have done more for Asian arts in the UK than probably any other entity. They have had their entire grant cut. The director of AMC, Viram Jasani, told me he was stunned by this unexpected savagery and took a week or two to gather his thoughts and mount a campaign. Sections of the media have started to swing behind it – in the last week an editorial in The Guardian simply said: “This is madness.”
