“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.

Orkos was originally released in 1979 on cassette. The only album by Egyptian singer Maha seems to have been little known. The liner notes for its first-ever reissue say “it was not a success when it was originally released. While nobody remembers the exact numbers, sales must have been very limited and the project was quickly forgotten about and no follow up release was produced.”

South-African cellist Abel Selaocoe is about to begin his third major concert in London in under a year. As the support artist for kora player Ballake Sissoko and cellist Vincent Segal at the Roundhouse in January, he received a lengthy ovation for his 30 minute set, having demonstrated an uncanny ability to play the audience as dexterously as he plays his cello.

After a burst of gun-shot drumming, “Hot Coffee” instantly hits its groove. Simple but insistent guitar, a rubbery bass line and electric organ all fall into line. For the instrumental’s two-and-half minutes, it is unstoppable.

“Gig Soul Party” is as tight but more ornate as the organ playing incorporates flourishes. There’s a spindly solo guitar line and some funky-drummer drumming too. But it’s as effective. Dance floors would have been crowded.

Although Raf Vilar grew up in Rio De Janeiro he has been based in London for over a decade, where his second album Clichê was recorded. It appears on a label operating from Malmö, Sweden. In keeping with this internationalism, what’s emerged isn’t wholly identifiable as a Brazilian album. His 2011 first was unequivocally titled Studies In Bossa. Now, the designation is more inscrutable.

On the last weekend of July, as they have every year since 1965, when an enlightened city council decided that Cambridge – like Newport, Rhode Island – would have a folk festival, thousands of people trekked to Cherry Hinton to enjoy what is now Britain’s premier folk event. One of the biggest in Europe and celebrated throughout the world, Cambridge is a calendar fixture and its return after the inevitable Covid absence was clearly very welcome.
