If you're looking for good vibes, you could do worse than watch people who've queued up for a surprise show by a megastar finally getting through the doors, having paid only a tenner. The buzz on the way into the Shepherds Bush Empire last night, in fact, was a real tonic – people whooping, spontaneously singing, grinning inanely. A quite peculiar mix of celebrities – Nick Grimshaw, Cara Delevingne, Alan Yentob and George Clinton – all took to their seats looking as excited as the 3,000-odd standard punters.

In a world where everyone is expected to be a “brand”, Gilles Peterson sets some very interesting precedents. Probably best known as a radio DJ – currently on BBC 6 Music, plus his globally syndicated Worldwide show – he also remains as in demand to play in clubs as at any time in his 25-year career, he runs the Brownswood label, and has his own Worldwide Festival, currently with winter and summer editions in different locations in France plus four years running in Singapore and one in Shanghai. And somehow his individual personality remains at the heart of all of this.

"We got 42 years of music to lay on you" is an audacious opening statement for any live band, but when the speaker is Phillip Bailey, lead singer in the current reincarnation of the legendary Earth, Wind & Fire, it is a statement of intent. Playing at the palatial Albert Hall in support of their new album Now, Then & Forever, the current line-up of young session players, complementing the core trio of Bailey, bassist Verdine White and drummer Ralph Johnson, proved without a shadow of a doubt that they still have the energy and skill to hold a crowd enraptured.

Having boundaries actually sets us free. So Neil Armstrong's wife argues. She is dogmatically keen to stop her husband rocketing off to the moon in the first scene of The Lightning Child – a groundbreaking show in so far as it's the first musical to premiere at Shakespeare's reconstructed wooden "O", opening last night. Armstrong (Harry Hepple in a space suit) does not agree with his spouse's imposed limits, however. A lunar voyage is, he says, his chance to become sublime.

Janelle Monáe’s much-awaited second album doesn’t disappoint. She navigates the ever-renewing waters of African-American pop invention, drawing on R & B, funk, gospel, rock and dinner jazz, with a sense of fun and a great deal of talent. She is a master of eccentric chic, sophisticated, with a hint of the (tastefully) bizarre.

When The Golden Age of Apocalypse, the first LP by Stephen Bruner, the American musician better known as Thundercat, was released in 2011, it was a revelation. Co-produced by Flying Lotus and taking its cues from electronica, prog, pop and funk, its sublime jazz sound united head-bobbing musos, fellow musicians (Bruner counts Dr Dre, Erykah Badu and Odd Future among his fans and collaborators) and critics.

The easy thing would have been for Omar to come back trading on nostalgia, made his seventh album a nice smooth jazz-funk set and reminded everyone what made them fall for his biggest hit, "There's Nothing Like This" from 1991. Indeed you might even think that's what he's doing, with a new recording of that song appearing here. The moment you put the album on, though, there is no question at all of a man resting on his laurels.

It's pretty impressive that at 74 years old, the drummer Jaki Liebezeit should still be one of the most vital musicians on the planet. Maybe not all that surprising, though. From the moment in 1968 when he switched from free jazz to the narcotic jams of Can, he pioneered a rolling rhythmic style that suggested infinite patience and a man comfortable in his body, and it feels entirely natural that his beats should keep on rolling into old age. “Liebezeit” translates literally as “Love Time”, and it feels like he really does.

We're extremely happy to be able to offer a free download of this live track by New York collective Mice Parade to mark the release of their seventh album, Candela, today. In its six minutes, this version of "Couches & Carpets" encapsulates much of the diversity that has made Mice Parade a cult act over the past decade - from indie introspection to expansive post-rock guitars, jazz-funk grooves to melodies and techniques influenced by anagramatically eponymous band leader Adam Pierce's wide research as an ethnomusicologist. 

It was one of those entirely unverifiable "facts" that music documentaries increasingly prefer over genuine insight: early on in this serviceable but routine overview of a truly stellar talent, we were told that Nile Rodgers’s guitar has “played on two billion dollars' worth of hits”. Who really knows? Who actually cares? You don’t measure the sheer joy of Chic’s “Good Times” or Sister Sledge’s “We Are Family” by counting the cash or doing the math. You simply use your ears.
