Dr. Feelgood was the first band I ever saw live, and I can still remember that frisson of expectation queuing up outside the Cambridge Corn Exchange in 1975. I didn’t even know who they were or what they sounded like, I simply had some pals who were soon-to-be-punks who’d got wind of the fact that these Canvey Island ne’er-do-wells were the harbingers of something new, something borrowed, and something blue. But the blues were only the starting point for "Feelgood" as we, necessarily, truncated their name.

In another lifetime, I walked into the Electric Ballroom in Camden Town through a portal into a new world: the cavernous dancehall was packed, and the "audience" being choreographed by cross-rhythms of Afro-Cuban and Brazilian ancestry in an atmosphere created by a 17-year-old jazz funk DJ called Gilles Peterson. I was witnessing the dawn of the New Jazz Age.

Nico Muhly didn't have to work much to puncture any atmosphere of classical recital formality at the Roundhouse: he only needed to be himself. Young, slightly dorky and very camp, wearing a black garment that blurred the boundaries between cardigan and bathrobe, and bantering lightly with the audience, the Vermont-born New York-based composer gave the impression that he couldn't take himself too seriously if he tried.

The prefix “Christian” can invite mockery. The suffix “rock” usually makes it worse. And a Christian Rock band celebrating 25 years in yellow and black Spandex? Surely that has to be a spoof. But I have news for you: Eighties Californian glam metal band Stryper are real, back, and tonight they rocked.

"So, we made it eventually." Having postponed this show two weeks ago due to the M1 doubling as a skating rink, Richard Hawley opened not with a song but an apology. It was hardly necessary. The sold-out Royal Festival Hall last night was prepared to forgive Sheffield's second-finest songsmith - after his chum Jarvis Cocker - almost anything.

The dominant look among all ages of the sell-out audience at the Barbican Hall last night was distinctly “smart-Bohemian”, with plenty of thick-rimmed specs, duffle coats and subtly outré hairdos visible as they took their seats and gave one another knowing nods on spotting the “Fruit Tree” motif in the stage décor. For Nick Drake, the fragile Cambridge-born singer-songwriter who died of an overdose of antidepressants in 1974 aged 26, is perhaps the perfect cult artist: utterly singular, too intense and serious to be appreciated in his short lifetime, but increasingly influential on the mainstream with each passing year.

I’ve never been quite sure whether Brian Eno is a musician, or somebody for whom music happens to be the end product of a chain of cognitive processes. Certainly it was music that powered him to prominence, either as the inventor of ambient music, a performer with Roxy Music, or as a collaborator with artists ranging from rock gods U2 and David Bowie to composers Harold Budd and Philip Glass.
