I'll be straight: I wasn't sure what to expect at this show, because I've never been a Björk fanatic as such. I loved – and saw live – The Sugarcubes as a teenager, I've raved to her Nineties Debut and Post era tracks, and I've enjoyed plenty more since, not least the intimacies of Vespertine [2001] and the wild expansiveness of Volta [2007].

theartsdesk meets Christine McVie on a sunny Friday afternoon in September; the Warner Brothers boardroom (with generous hospitality spread) is suitably palatial. We’re the first media interview of the day, so she’s bright and attentive. McVie was always the member of Fleetwood Mac who you’d want to adopt: the most approachably human member of a band constantly at war with itself.

There's a lot of neurosis these days about retro-ism and lack of innovation in music, as if the shock of the new is all that gives things value. Of course, this is something worth keeping in mind: we certainly don't want to end up in a Keep Calm And Carry On world of faux nostalgia for golden ages that never existed, ingested as an analgesic as the present crumbles around us. But taken as dogma, it becomes a very one-dimensional way of looking at things, and can stop us appreciating how much newness there is in our ever-complexifying relationships to the past.

De La Soul are the posterboys for creative longevity in hip hop. While some contemporaries have maintained a presence by relying on “heritage” status while going in ever-decreasing circles musically (hello, Public Enemy), the trio – still in their original line-up almost 30 years on – have never stood still. They've maintained strong relationships with the hip hop world, both underground and mainstream, while reaching out to interesting alternative collaborators (Yo La Tengo, Gorillaz etc) who've put them in front of new audiences.

The accelerating glorification, in the West at least, of the handmade is a fascinating phenomenon, perhaps a subliminal fight back against overwhelming industrialisation and the age of the robots. And perhaps nowhere is the admiration and commercial possibility accruing to the handmade artefact more evident than in British companies who can label themselves as By Royal Appointment.

Perhaps as a hopeful harbinger for Paul Simon's new album Stranger to Stranger, Disturbed recently topped Billboard's Mainstream Rock Songs chart with their flabbergasting version of Simon's 1965 song "The Sound of Silence". However, while vocalist David Draiman could launch a career as a new kind of Wagnerian baritone on the strength of his extraordinary performance, Simon himself is headed in a less stentorian direction.

Questions of what is authentic and what is retro get more complicated the more the information economy matures. Music from decades past that only tens or hundreds of people heard at the time it was made becomes readily available, gets sampled by new musicians, and passes into the current vernacular. Modern musicians play archaic styles day in day out until it becomes so worn into their musculature that it reflects their natural way of being. Tiny snippets of time that were once meaningless become memes that are shared and snared into the post-post-modern digital tangle.

He knew.

18 months of dealing with cancer, and rather than withdraw and rest – as he'd done before – David Bowie knuckled down made a record as intense and disturbing as anything he's done before. The Next Day was a worthy return to the fray but Blackstar... Even before we heard the terrible news, just taken on its own merits, Blackstar was something else. And now, knowing that he knew, it's absolutely fearsome in its confrontation with death.

For some musicians operating on the leftfield, achieving accessibility or commercial success means compromising their unique vision. Not so with Los Angeles singer-songwriter-producer Julia Holter. Her first three albums – four, if you include 2009's home-burned CDR Celebration – were intriguing, if blurry, windows into a complicated inner world, within which intensely felt dreams and extraordinary erudition tangled up into constantly moving patterns, but the haze rarely revealed any distinct shapes.

There's a new kind of forum for electronic musicians. Certainly not a rave, and not just a recital to earnest nerds, built on a kind of patronage, but a long way removed from a standard corporate gig where you're just providing the interchangeable soundtrack to X or Y product launch. The realm of the technology party, often seen at conference-festivals like Amsterdam Dance Event and Sónar, but increasingly as a standalone thing throughout global cities, is something very 21st century, very odd, and still to be negotiated.
