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.

Hawklords were one of the first splinter groups from late Seventies Hawkwind, when Dave Brock and Robert Calvert  were joined by bassist Harvey Bainbridge, Pilot’s Steve Swindells and drummer Martin Griffin for a short-lived but brilliant incarnation.

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.

Natasha Khan has taken a fascinating trajectory through the music world. As Bat For Lashes she first came to public attention as part of an early-2000s wave of psychedelia, allied in particular to the furry starchild Devendra Banhart. But her high drama electropop-tinged sound was as far from Banhart's all-organic “freak folk” as it was from the fiddlier laptop-driven sound of folktronica, and she ended up occupying a space all her own.

In a way that is reminiscent of fellow Swedes and label mates Goat, Hills play a primal psychedelia that draws from a far broader spectrum of sounds than the usual garage rock and motorik grooves of their British and American fellow travellers. On Frid, their third album, vocals are largely put aside in favour of spaced-out instrumentals or chanting that suggests medieval plainsong fed into an effects box.

"This ain't the Summer of Love," sang Blue Oyster Cult in 1975. Judging by this intriguing new drama, it might not really have been the Summer of Love in 1967 either, as David Duchovny's Detective Sam Hodiak picks his way through the dope and the kaftans and finds himself on the trail of a menacing little scumbag called Charlie Manson.

There is something strange happening in mainland Europe at the moment. Perhaps this has been spurred on by a feeling that the old certainties of the past aren’t quite so solid, but a mind-expanding psychedelia with an eye for the dance-floor and free of navel-gazing pastoral whimsy has been springing up in all kinds of unexpected places.

There’s been a real sense of expectation surrounding Kevin Parker’s new offering, with rumours of a disco album from the saviour of psychedelia after a conversion to the joys of the Bee Gees while on mushrooms. That sounded an interesting proposition – one that could make the mind bogle.

An all-analogue space-rock, Krautrock-influenced, motorik-driven psychedelic ride on Saturn’s rings, Gwenno’s Y Dydd Olaf is a treat from start to end. Her sweet but dislocated vocals mesh with snappy bass guitar, bloopy synths and the otherworldly atmosphere of Ralph & Florian Kraftwerk.
