The Laugharne Weekend has become a fixture in the crowded calendar of festivals that now punctuates not just high days and holidays but the whole six months that make up British Summer Time. Carving a niche for itself as a halfway house between literature and music, Laugharne’s success is built on two key factors.

The 18th-century Omani fort in Zanzibar is silhouetted against a clear African night. Nneka, a bird-like Nigerian female artist in shabby leggings, is hammering out “Vagabonds in Power” on an open-air stage inside the fort, just metres from a sea of entranced faces. The song is a poke at Africa’s leaders, specifically their part in the Niger Delta mismanagement and related death and corruption scandals. With a voice reminiscent of Nina Simone, and the emotional clout of Billie Holiday, Nneka delights the predominantly African crowd attending the Busara festival.

You may be feeling Titanic fatigue by now, the last straw being the so-so Julian Fellowes TV romp which heads, as Adam Sweeting points out elsewhere, “an epidemic of TV programmes” this week.

It began with a warning. Opening the fourth Tallinn Music Week, Estonia’s President Toomas Hendrik Ilves cautioned, “In a free society, it’s risk-free. In an un-free society, it’s not risk-free. It’s not all fun.” From behind a hotel conference room lectern, he then began rolling a video of Russia’s Pussy Riot being arrested in Moscow a few days earlier. Not everyone can make their point, make their music, choose how they want to get it across.

Krzysztof Penderecki's Polymorphia for 48 string instruments dates back to 1962, and still stands as one of the grand milestones of the avant-garde. It epitomised the Polish composer's technique of "timbre organisation", in which the plucking and bowing of strings was merely a small part of an astounding array of effects.

So Homeland is here, and mid-ranking-CIA-operative Claire Danes is chasing Marine-Sergeant-and-possible-al-Qaeda-double-agent Damian Lewis all over the shop (but really only in their heads, so far), and neither of them is getting anywhere fast, so Claire goes home for a kip and sticks on some relaxing music, and would you Adam ‘n’ Eve it? – another bloody jazz nerd!

Although the four days of Norway’s 15th by:Larm Festival were dominated by the presentation of the second annual Nordic Music Prize, there were plenty of other distractions: a sobering tour of Norwegian black metal’s infamous sites, a talk by legendary Nigerian drummer Tony Allen, what felt like millions of shows in millions of venues, and weather confounding all expectations of what Oslo ought to be like in February.

Something falls with a clatter from one of Dom Flemons’s pockets. The Carolina Chocolate Drops’s banjo player, guitarist and all-round picker and plucker has a lot of pockets. Earlier, he’d produced a pipe from one, a tobacco pouch and tuning pipes from others, but what has just dropped on the table are his bones. His musical bones. The ones whose rhythms are rarely far from the heart of his band. “You never know when you’re going to need them,” he says. “Sometimes you just get bored."

Right, out with it: who else had their Valentine’s dinner-out ruined by 36 consecutive requests for Whitney Houston? Not even the entire back-catalogue, either: just “(And I-ee-I-ee-) I…”, over and over.

Of the many statements and tributes coming from peers and fans following the death of Whitney Houston last Saturday, perhaps the most unlikely of all was the one from the website of Diamanda Galás. One mightn't have imagined the most fiercely uncompromising singer of her (or any other) generation rushing to the defence of someone widely seen as the patron saint of the just-add-water divas of The X Factor age. But Galás knows a thing or two about death and decay, and has also praised Houston in the past, declaring her to have "ended the line" for modern R&B singers.
