If it seems mythical that a singer-songwriter in his early seventies has made an album this vital yet so timeless, then it’s worth pondering that Man & Myth is Roy Harper’s first for 13 years. In 2011, he celebrated his 70th birthday on stage but in the decade before his profile had been low, with time in his Irish home seemingly filled by anything that wasn’t creating new music. It might be making up for lost time, but Man & Myth’s 23-minute closing epic “Heaven Is Here”/“The Exile” is a career highlight.

MGMT’s last album, 2010’s Congratulations, defined a modern psychedelia of the highest order. Bold of sweep, full of ambition and tinged with the airs of defeat and desperation, it set Ben Goldwasser and Andrew Van Wyngarden up as ones to watch: a duo whose early electropop-inclined work had been left far behind. It’s unfortunate then that their self-titled third album does not take them even further out. Instead, MGMT is the sound of a band stuck in low gear.

Roky Erickson: Don’t Slander Me, Gremlins Have Pictures

Marianne Faithfull hasn’t got much time for her 1968 starring vehicle The Girl on a Motorcycle. In her autobiography Faithfull, she described it as “terrible…soft porn” and said of her co-star Alain Delon that he was a “pompous git". The trailer promised that while seeing it “you know the thrill of wrapping your legs around a tornado of pumping pistons”.

Characterising a country’s music by its most successful exports or what seem to be typical local styles is inevitable. With Iceland, the home of Björk and Sigur Rós, it’s easy to assume that ethereality, otherworldliness and plain oddness rule the roost. Of course, that’s not the case. The artists awarded the Kraumur prize for the best albums released in 2012 testify to Iceland’s broad musical palette. On the next page, our look at the Kraumur winners ranges from the hotly-tipped Ásgeir Trausti to, among other surprises, home-grown reggae.

Michael Hurley: Armchair Boogie / Hi Fi Snock Uptown

When Tunng started out in 2005, they were a peculiar proposition. Treading a fine line between Heath Robinson ramshackle and meticulous high-tech, ancient and hyper-modern, bone percussion and glitchy electronic sparkles, they certainly deserved the then-popular term “folktronica”. Though their melodies were unerringly catchy, their lyrics were so out-there, their lineup so unorthodox and their sound so psychedelic it was never likely they'd be more than a cult act.

Dr. Feelgood: Taking No Prisoners (with Gypie 1977-1981)

Continuing its voyage through Scandinavia’s music, theartsdesk opens the latest chapter in Norway with Still Life With Eggplant, the 16th album from Trondheim’s prolific, long-lived, occasionally challenging and always vital Motorpsycho.

It's pretty impressive that at 74 years old, the drummer Jaki Liebezeit should still be one of the most vital musicians on the planet. Maybe not all that surprising, though. From the moment in 1968 when he switched from free jazz to the narcotic jams of Can, he pioneered a rolling rhythmic style that suggested infinite patience and a man comfortable in his body, and it feels entirely natural that his beats should keep on rolling into old age. “Liebezeit” translates literally as “Love Time”, and it feels like he really does.
