William Finn and James Lapine’s musical – which combines two linked one-acts, March of the Falsettos and Falsettoland, set in late 1970s/early 1980s New York – picked up Tony Awards in 1992 for its book and score, and was nominated again in 2

It’s half a century since Iggy shrieked that it was “No Fun”, that it was “1969, OK”, that he wanted to be your dog. His original Stooges and his storied cohorts David Bowie and Lou Reed are all no longer with us. The Ig is the last man standing and he knows it. 72 years old, he’s the lizard-punk shaman figurehead who, off-stage, is a considered literate gent, the radio presenter with the velvet croak. His new album acknowledges that he’s now an old dude.

Diamond Head was Roxy Music guitarist Phil Manzanera’s first solo album. Released in May 1975 and recorded the previous December and January during a lull in his parent band’s activities, it hit shops between Roxy’s Country Life and Siren albums. Singer Bryan Ferry had done a short solo tour in December 1974 which culminated with a show at The Royal Albert Hall where he was backed by an orchestra. Manzanera took a different tack.

The core paradox with powerpop is that most of those who sought to create the perfect guitar driven, hook-laden pop song failed to score hits. Come On Let's Go! – Power Pop Gems From the 70s & 80s is stuffed with the classy and memorable, but under a third of its 24 participants had any sort of chart profile. And, for 20/20 and Wire Train, it was fleeting and ultimately inconspicuous.

Don’t Look Now is beautiful in its dankness – an eldritch psychological thriller that follows a grieving father’s stream-of-consciousness as it flows into deadly waters.

Cindy Sherman predicted the selfie, so goes the claim. From our current standpoint, it is all too easy to analyse her many hundreds of photographic self-portraits made since the late 1970s as cultural forebears of the digital medium.

Britain’s musical eruption of 1977 wasn’t just about the now. As the new box set 1977 – The Year Punk Broke amply demonstrates, the flux allowed more than first-timers through the door. Seasoned gig-circuit regulars Stranglers got a leg up. A band called The Rings, featuring former Pink Fairies, Pretty Things and Tomorrow member Twink, issued their one single in 1977.

“As much as I love New York City, it’s all too obvious that Cleveland is about to become the musical focal point that the Big Apple has been on and off since the beginning of the century,” wrote Peter Laughner in October 1974. “I want to do what Brian Wilson did for California and Lou Reed did for New York.” To a degree, the new five-album/five-CD set Peter Laughner achieves this, albeit 42 years after his death.

When he gave Martin Dysart, the troubled psychiatrist protagonist of Equus, a line in which he speaks about “moments of experience” being “magnetised”, Peter Shaffer might almost have been talking about theatre itself. It’s a phrase that comes close to catching what we feel when we're transfixed by the hard-to-predict coming-together of play, performance and production that marks the highpoints of drama.
