There's a lot about stoner culture that smacks of earnestness, and The Dark Side of the Moon has been at the heart of a good deal of that. The number of long, dreary, late-night conversations that must have taken place over “doobs” and “munchies” about its themes of life, death, madness, desperation and all the rest doesn't even bear thinking about.

There are numerous tribute versions of The Dark Side of the Moon, by everybody from jazzers to electronica merchants, but the Amazon Surf version must be the most esoteric. Amazon Surf music is one of the more curious music phenomenona I've stumbled on.

In March 1973, John Lennon was 33. Elvis was 38. There was barely a musician, in the sense we understand it, over 40. No one with a mortgage – or hardly anyone – was into rock’n’roll. The Dark Side of the Moon changed all that. It made rock middle-aged.

In 1973 certain world events carved themselves, a bit like the faces on Mount Rushmore, deep into the landscape of the late 20^th century. No sooner had Richard Nixon begun to end the Vietnam War than Watergate broke. In the autumn Allende was overthrown by Pinochet in Chile; Egypt and Syria’s attack on Israel ignited the Yom Kippur war. A global oil crisis was to leave western economies strapped.

The sound of a heartbeat. A metronomic ticking. Two men confessing that they’re mad (even if they’re not mad) as a cash register chings. Another man’s manic laughter. A harsh industrial grinding noise. Screams. And then some rock music, Olympian in its distance and instantly cinematic, but with a hint of the blues…

Family: Once Upon a Time

With David Bowie’s return prompting thoughts on British art rock, it’s apt that Dutch Uncles’ third album is hitting the streets now. A through-and-through example of smartly constructed pop, this would in another era have been called prog rock.

No one would have believed in the last years of the 1970s that human taste was for concept double albums based on novels by HG Wells about invading Martians. No one could have dreamed that the era which spawned shouty gobshites in skinny trousers would also find house room for the alien union between late Victorian science fiction and pompous orchestral pop. Yet, across the gulf of time we can confirm that this did indeed happen. And much as they did in the flash-forward conclusion to the original album, the Martians are invading all over again.

Muse are not cool. For a minute on leaving the tube station I did think they'd broadened their appeal quite dramatically before realising that a fair section of the people around me were heading to Giants of Lovers Rock show also at the O2 complex last night. But no, their audience, judging by those heading for the main arena, are a fairly even split between hyper-mainstream V Festival demographic and slightly misshapen indie/goth kids, not really much more rock'n'roll in demeanour than, say, a Coldplay crowd, but very dedicated.

If Grizzly Bear’s name is unfamiliar to you, you’ll certainly know some of the indie-folk bands they’ve influenced. These include Bon Iver and Fleet Foxes, two of music’s more unlikely recent successes. Brooklyn’s Grizzly Bear never seemed to want that mass appeal. This autumn they followed 2009’s melodic Vecktamist with the rather more difficult Shields, whose songs suggested they might sound better live. Last night a 5000-strong crowd at the Brixton Academy was hoping so.
