The Queen's given everyone an extra bank holiday, so while you rest up over the Easter holidays, start planning your next downtime with theartsdesk's definitive clickable festival guide for the summer. We have headline listings and links for all the UK festivals this year, from rock by the lochs to DJs in London parks, and catching classical and opera on the way.

With the subject of the legitimacy of the label “world music” having just had another airing in The Guardian, it seems fitting that Mali’s favourite musical couple should be releasing their least “world music” album to date. For essentially, Folila (which translates as "music" in Bambara) is a blues/rock album.

In the early Eighties Peter Gabriel was the ne plus ultra of arty, experimental margin-hangers, breaking cover occasionally with an improbable hit single before “retreating back into the bushes with my normal crowd”. His fifth studio album, So, changed all that. Its lead single “Sledgehammer” strutted over the dividing line between cult kudos and mass-market kerching, leading Gabriel and the rest of this darkly soulful album straight into the arms of the mainstream. After 1986, he was one of the big beasts.

Peter Gabriel announced WOMAD’s 2012 festival in Sicily this afternoon. It’s a year of anniversaries for the annual showcase of world music, with 2012 also marking the 30th year for Britain’s big brother festival. On a wintry afternoon, sharply contrasting with Sicily’s climate, Gabriel was joined at London's Italian Cultural Institute by Carlo Presenti, the institute's director, and Roy Paci (pictured below right), Sicily’s cultural polymath and musician whose past collaborators have included Manu Chao and the Netherlands' The Ex.

The Mayans say 2012 is The End, so this may be the very last round-up of the year. I saw possibly the best Shakespeare I’ve ever seen – a chamber version of King Lear at the Donmar Theatre directed by Michael Grandage with Derek Jacobi as the mad old King, presenting a perfectly credible mix of vanity, vulnerability, craziness and tenderness. The final scenes with Lear and Cordelia were among the most affecting I’ve seen in a theatre.

2011 was an excellent year for highly original music from female musicians, two of whom brandished ukuleles yet found quite different ways of using them.

“It’s cultural imperialism,” a middle-aged gentleman felt compelled to say to me, presumably because I was the bloke with the notebook. “Then all pop music is cultural imperialism,” is what I should have fired back at him, had I not been so immersed in the transcendental racket of tussling brass and distorted guitars that had almost made him inaudible. But instead I took the scenic route of pointing out that this legend of 1970s Ethiopian jazz would hardly have spent the last seven years playing with these white Dutch musicians if he had felt he was being exploited.

That Alan Yentob gets around. I’ve run into him backstage during Jay Z's set at Glastonbury and in a jazz club in Poland, and here we found him in Rajasthan fronting a fascinating and well-shot programme, albeit workmanlike rather than really inspired, mostly set in one of the richest traditional music areas of India.

In the age of Skype and no-frills budget travel, frontiers barely exist – at least if you’re not an immigrant or refugee. World music is as much about boundary-breaking and fusion these days as it is about discovering the unsullied treasures of what UNESCO calls the "intangible heritage". Contemporary global sounds can feel like an opportunistic marriage between musicians who have little in common, or else a more appropriate union with some basis in cultural kinship or history.

Some critics have lazily compared Baloji to Somali rapper K’nann: both are African rappers who had lucky childhood escapes from countries about to descend into war and chaos, but beyond that they seem to have quite different approaches to what they do. K’naan is as much a pop musician and poet as he is a hip-hop artist, firmly concentrating on melody, song structure and hooks. Whereas Baloji, at least on the evidence of this album, seems to want to engage more with roots music while finding ways for his rhymes to fit in with already established musical idioms.
