In an age where things change at a lightning pace, where we are programmed for progress, touchstones are crucial. There’s a need for something we can rely on to remain solid, unchanging and free of the burden of momentum. The noise produced by Dinosaur Jr, which comprises J Mascis, Lou Barlow, drummer Murph and others, is just such a thing – gloriously monolithic and fondly familiar.

In the early 2000s, a club called Trash in London, run by DJ Erol Alkan, introduced a wave of indie teenagers to the joys of electronic music, giving them a way into club culture that was all theirs and not beholden to the superstar DJs of the acid house generation. A generation of bands would form directly or indirectly influenced by it – and by the end of the decade, there was a mini wave of bands like Friendly Fires, Late Of The Pier and Wild Beasts, who integrated electronic sound into a rock band format, and brought a bit of disco glitter and androgyny to their image to boot.

Purple’s 2014 debut album, (409), was a burst of party punk straight out of Texas that deftly avoided crass clichés while letting the good times roll. Sophomore effort Bodacious won’t disappoint those who were bitten by the Purple bug the first time around and might even entice new listeners along the way. In particular, a hefty dose of the funk has been added to their exuberant groove, with Joe Cannariato giving his bass a good seeing to where previously he might have sat back.

Thirty-three minutes is not long for an album. What actually counts is not length but what is said and its impact. Norway’s Hedvig Mollestad Trio know what they are doing and over Black Stabat Mater’s 33 minutes they do it with such clarity, force and panache there is no need to say any more. This is exactly what an album should be: a coherent statement.

While many acts have deployed the live album as a stop-gap or an easy money-spinner, some of Neil Young's best work was recorded live – Rust Never Sleeps, Weld and Arc-Weld, Live at Massey Hall 1971, the enigmatic Time Fades Away and so on. As an artist who works spontaneously and intuitively, much of his studio work is effectively live anyway.

The names may be unfamiliar, but Folque and Undertakers Circus are as good as better-known bands. Despite being musical bedfellows neither Norwegian band is as esteemed as, say, Trader Horne and Trees or Colloseum and Lighthouse. Folque issued their eponymous debut album in 1974. Despite line-up changes, the band was active until 1984. Undertakers Circus issued two albums, the first of which was 1973’s Ragnarock. The original band ran out of steam around 1976. Original pressings of Folque fetch between £40 and £80.

Led Zeppelin are an icon of musical class. Train, even their admirers must admit, are not. With this faithful, perhaps too faithful cover, the credit can only flow one way. Responses to this album have been a touchstone of journalistic identity, with our competitor sites posting sarcastic reviews, only to be accused below the line of snobbery, ignorance, and, most damning of all, hipsterdom.

The Janis Joplin bio-doc has been a long time coming. The rock star’s family were notoriously cautious about exposure: who wouldn’t be, with a career so tragic and brief?

As it happens, their collaboration made possible the inclusion of the rock star’s poignant letters home, which the documentary uses to great effect throughout, revealing something of the singer’s inner life and vulnerability, in contrast with her careful self-presentation as a mixture of bad girl, sex bomb and Etta James impersonator.

It's peculiar seeing any band come back together after a serious length of time, but when that band were part of your adolescence the cognitive dissonance is exponentially increased. Along with the likes of Ride and Slowdive, Lush were a band linked to the “shoegaze” indie sound born in the Thames Valley at the very end of the Eighties, and my main experience of them was at ear-bleed volume in dangerously packed-out, toilet-stall-sized venues around the area, my fringe covering my face and all the hormonal intensity of youth amplifying the effect of the sound.

It's the first night of The Fall's four-night residency at The Garage in Highbury, north London, a suitably small venue to get the full visceral rub of the current group – Elena Poulou on keyboards, guitarist Peter Greenaway, drummer Keiron Melling, and bassist Dave Spurr.
