Milton Nascimento is 76. Physically, he is quite frail; he had to be helped carefully onto the stage and then up into a high stool for this London concert by a couple of band members. But that arrival and rather ungainly progress were, as one might expect, given a welcome befitting this hero of the Brazilian musical world. The completely full Barbican Hall was willing him on.

In Time: The Best of R.E.M. 1988–2003 was issued by Warner Bros. in October 2003. Hitting shops in time for Christmas, it mixed hits like “Everybody Hurts”, “Man on the Moon” and “Orange Crush” with album and soundtrack cuts, and a couple of previously unissued tracks. Released as an 18-track CD, it was initially issued as double-disc set with the additional material drawn from B-sides, more film soundtracks and live performances.

They showed up with a 30+ song setlist, four costume changes and a floating platform, but the strongest moment of the Backstreet Boys’ tour was when they dispensed with all of that for an a cappella version of “Breathe”, from new album DNA.

“Like we used to do it,” Howie Dorough explained. “Not a lot of people know we started out as an a cappella group.”

In a post Ed Sheeran world, with a glut of acoustic singer-songwriters like Lewis Capaldi, Tom Walker or Odell, James Bay, Jack Savoretti – all of whom are big on poignantly penned balladry, phonic flair and harmonious melody – is there room for another young male artist to make waves in the indi-folk arena?

“Lenny’s coming! Lenny’s coming!” When the lights go down at the O2 tonight, it’s not just the small child behind us who’s excited.

Tomorrow, Martin Scorsese delivers, via Netflix, two hours and 22 minutes of screen time devoted to Bob Dylan’s Rolling Thunder Revue, following on from the release last week of the latest Bootleg Series boxed set, 14 CDs covering five full concerts from November and December 1975, as well as rehearsals and sundry soundboard cuts from

Although Marty Wilde will forever be inextricably linked with the late 1950s British rock ‘n’ roll wave he rode, his career did not peter out as musical styles transformed. While he didn’t have the high-profile mutability of Cliff Richard or claim a niche like the moody Billy Fury, he was enviably chameleonic.

A hushed expectation filled the Queen Elizabeth Hall on Friday night in advance of the return on stage of the legendary Le Mystère des Voix Bulgares (now rebranded as The Mystery of the Bulgarian Voices), who graced Kate Bush’s 1989 classic The Sensual World with their astonishing style of throat singing, combining drones, quarter tones and complex rhythms, harmonies combining in marvellous permutations, seemingly colliding into each other from diff

Percussionist Pedrito Martinez is one of those musicians who forces you to re-think what instruments are capable of – while making you wonder if there is actually anything he can’t do. He plays congas, batá drums and bongos with breathtaking facility and flow. He sings everything from Yoruba chants to “Quizás”. He dances. And he can turn a side drum and a hi-hat (no sticks, all played with hand/foot) plus cajon drum as if by magic into a rock drum kit.

Only those who’ve just popped in from an early 20^th century Tennessee cotton field will have recently observed more pairs of dungarees in one place than at Red Rooster. It’s a festival that prides itself on a rich diet of Americana alongside a defiantly retro aesthetic.
