Over 1974 to 1978 Graham Collier issued five albums on his own imprint Mosaic. There was another in 1985 and eight releases on Mosaic by other musicians, but for its first four years the imprint was dominated by the British jazz composer, bassist and bandleader’s own work. In the same period, three books Collier had written came out.

It’s Christmas 1971 in New Prospect, a suburb of Chicago, and pastor Russ Hildebrandt has plans for time alone with Frances, an attractive young widow who’s just moved back into town.

While there’s undoubtedly some of “Papa Was a Rollin' Stone” in Rare Earth’s “Come With me”, another correspondence also immediately springs to mind – the Melody Nelson-era Serge Gainsbourg. And maybe, due to the female moaning, the “Je T’Aime”-period Gainsbourg too.

“There should be some kind of spirit there which is outside whoever is in the band. The spirit of the band, wanting still to play songs, real songs, wanting to play complicated music to a certain extent. Fairly dense arrangements, also difficult pieces of music, not to be difficult but just because that’s a challenge. To do all that and then also play with a degree of anarchy, chaos, and fire and spirit. That’s the spirit of Van der Graaf.”

Along with Tangerine Dream and Jean-Michel Jarre, Vangelis is a key figure in the development of - to be loosely colloquial about it – trance and chill-out electronica. His 1970s work was proggy trip music, laced with classical aspirations that later came into their own. Artists from Sven Väth to Air to Enigma owe him a debt, as do those involved in the current boom in soothing electro-classical sounds.

When The Specials returned with their chart-topping 2019 album Encore, it was a wonderful surprise. As well as being their first in nearly four decades (excluding material by alternately named intermediary incarnations), it proved they were more than an endlessly touring heritage night out for ageing rude boys. Critics of their reappearance on the tour circuit claimed they were washed up without the band’s original driving force, Jerry Dammers.

“Reaffirmation” is the sound of a San Francisco ballroom in 1968. The 12-minute long track opens mysteriously with what might be a Mellotron on the flute setting. A bubbling bass guitar arrives, along with jazzy piano. At 02.50, the tempo picks up and the guitar, which until then has delicately picked its way through the arrangement, begins to soar. There’s a vaguely funky section and, just over half-way in, a dive into an almost free-form spiralling section. This is top-notch psychedelia.

“She is a 20-year-old white New Yorker who sings like a 55-year-old black lady from Mississippi. The experts say she will do for soul pop what Dylan did for folk.” Lillian Roxon’s verdict on Laura Nyro appeared in her ground-breaking 1969 book Rock Encyclopedia, issued before Nyro’s third album New York Tendaberry.

Following the death last year from COVID-19 of keyboard player Dave Greenfield, it appears the The Stranglers’ five decade journey may finally be drawing to a close. They bucked all odds by maintaining a path after singer Hugh Cornwall left in 1990, and the last two decades, especially, have seen them hold steady, both as a live draw and with critically respected albums.

Toyah, always a one-off, has been a surprise star of the COVID-19 lockdowns. Her YouTube Sunday Lunches, kitchen-filmed cover versions with her husband, King Crimson’s Robert Fripp, have been celebratory shared moments, jaunty, unlikely, silly, revelling unashamedly in pop music (and, bawdily, in her own physical attributes!).
