“Yerimayo Celebration”, which opens Baaba Maal’s brilliant and superbly paced new album, sets the tone: it starts in the mists of time, as it were, drawing deep on the minimal soul of traditional West African music: a plucked ngoni, and a haunting voice. The spirits have been summoned.

Then, the song explodes, driven by the rhythmic clatter of the sabar drums, so characteristic of the region, with subtle voice distortions and electronic effects. This is fusion of the ancient and new that works wonderfully.

Ahead of two spring dates in the UK, Rodrigo y Gabriela release their seventh studio album, In Between Thoughts… A New World, a beguiling set of guitar-based music that has echoes through time and hints of rumba-flamenco and occasionally the heavy metal that brought the two musicians together in their native Mexico City back in the 1990s.

This is an enchanting album which brings together four outstanding musicians, brilliant in their own right, but also adept at the kind of collaboration in which the whole is greater than the sum of the parts.

One of the greatest things a musical artist can achieve is world building. That is, creating a distinctive type of environment, language and coordinates for everything they do such that the listener is forced to come into the musical world, and to engage with it on its own terms rather than by comparison. It’s something that musicians as diverse as Prince, Kate Bush and Wu-Tang Clan achieve have achieved, likewise plenty of more underground creators too.

Steve Mason has been impressively blunt about the inspiration behind his fifth solo album. “To me, this record is a massive “Fuck you” to Brexit and a giant “Fuck you” to anyone that is terrified of immigration,” he’s said, “Because there is nothing that immigration has brought to this country that isn’t to be applauded.” Thus, these 12 songs are riven not only with lyrical pith but also sounds borrowed from an international sound palette.

“Ka Huma” by Ivo Nilakreshna sounds as if a jazz band was taking on rock ’n’ roll. There’s a swing and sway, busy rhythm guitar and a lead female voice singing a yearning melody. An instrument which seems to vibes is in there. But there’s more than the familiar elements. Most of the influences are unrecognisable.

The Beatles loomed over everything else. It wasn’t inevitable, but the arrival of the revealing Revolver box set and Peter Jackson’s compelling Get Back film confirmed that there is more to say about what’s known, and also that there are new things to say about popular music’s most inspirational phenomenon of the 20th century.

"Descarga Royal" by Los Royal’s de Pucallpa opens proceedings. After flurries of wobbly wah-wah guitar, a driving percussion bed interweaves with a rolling guitar figure. Then, about two minutes in, the guitarist steps on the fuzz pedal. Groovy. Psychedelic too. The band’s name is taken from the tropical east-Perú city of Pucallpa, located on the Amazon tributary river Ucayali.

The Oslo World organisers are at pains to point out that, despite the name, they are not a “world music” festival. And with good reason, really. There may have been a few familiar WOMAD veterans headlining over the week-long event – Senegal’s Youssou N’Dour, Malie's Fatoumata Diawara, the queen of Cuba Omara Portuondo – but the emphasis was emphatically not on any kind of beads-and-bongoes authenticity.

A minute before coming on stage, the audience is asked to observe a minute’s silence for the victims of the Halloween tragedy in the central Itaewon district of the South Korean capital of Seoul.
