In the run-up to the release of his second album Grapefruit, Kiran Leonard has revealed the musical touchstones which map out his world. Boredoms, Kate Bush, the jazzy French Canterbury-rock types Etron Fou Leloublan, Fela Kuti, Swans, Scriabin and Sleaford Mods all colour his prog-tinged vision of music. And he looks elsewhere for ideas. The album's “Ondör Gongor” takes its title from a Mongolian giant while “Half-Ruined Already” is inspired by a Werner Herzog film.

The 100 Club is dark. Really dark. People are shrouded in the ink-light. I think it’s to save their embarrassment as they order a drink and realise they’ll have to either apply for a loan or sell a child in order to get drunk. In any case, the indoor gloaming provides the perfect setting for the opening act of the evening, Demian Castellanos. The creative helm of psych-rock act The Oscillation, he's on his own tonight with a wordless solo set showcasing new material.

Had he not become one of the pivotal members of Pink Floyd, it's not difficult to imagine that David Gilmour might have become an academic like his father Douglas (who was a lecturer in zoology and genetics at Cambridge), or maybe a high-flying lawyer with leftish inclinations. Despite having been at the vanguard of rock music in its greatest and most extravagant years, Gilmour was never a likely candidate for a dissolute life of rock'n'roll hedonism.

There's something reassuringly resistant to modernity about Jeff Lynne. In much the same way that his cast iron Brummie accent and demeanour have remained unchanged despite decades in Los Angeles, so his music remains in a late 20th century interzone – its real concerns being the songwriting of the Sixties and the huge, glossy production values of the Seventies and Eighties.

As part of BBC4’s continued course of musical regression therapy, we revisited a time of wide-eyed innocence, when ideas were big and pupils even bigger. The Sixties had swung and now they were set to start spinning as people looked to the past for inspiration, and to the future with aspiration.

As well as releasing electronic music on Ron Morelli’s feted L.I.E.S. label, and the sporadically brilliant Ghost Box, as well a particularly impressive outing on Static Caravan (as Primitive Neural Pathways), Steve Moore is the bass- and synth-playing half of Zombi. On Shape Shift, a heavier, darker and more rock-sounding record than fans of 2009’s Escape Velocity might be expecting, he is doing his utmost to show the acceptable face of horror-suited post-rock.

From its title-track opening cut to the final moments of its closer “Sova”, Allas Sak is recognisably a Dungen album. The musical dynamic between the Swedish quartet’s members and their collective sound is so distinctive that they effectively constitute a one-band genre. Allas Sak does not have as many dives into a jazz-informed inner space as its predecessor 2010’s Skit I Allt, and is also not as pastoral.

It’s nearly 40 years since bassist Steve Harris formed Iron Maiden and much has changed since then. Singer Bruce Dickinson has learned to fence, fly and kick cancer in the cock, and the band have continued to release albums – albums which, though rarely hitting the high points of their Eighties heyday, have often been pretty decent and admirably ambitious in scope.

Normally, if an album as good as The Man Who Sold the World had itself sold the sum total of sod all on release, it would have been lost, then found, before becoming a fêted rarity, exchanging hands for hundreds while bootleggers had a field day. The fact that it was a David Bowie album meant that, despite the initial indifferent shrug from the buying public, it’s shifted more than a million and a half copies. It remains, however, overlooked and underrated by many.

Almost a decade ago, I went to a disappointing festival in Holland. Driven to distraction by the crowd – a sixth-form disco stuck between the third and fourth circles of Dante's inferno – I, on the advice of a friend, went to see Muse. Their theatrical pomp and overblown, muscular attack took the top of my head off and replaced my brain with a great big lump of wallop.
