Pete Shelley’s departure from Buzzcocks felt abrupt. When he left the Manchester band which had been integral to British punk since 1976, the other members thought it was still a going concern. Shelley had reached a different conclusion.

Johnnie Taylor’s big break came with the ever-fabulous September 1968 single “Who's Making Love.” His ninth 45 for the Stax label, it went Top Ten on the Billboard Hot 100. Up to this point, the Arkansas-born singer had been on the R&B charts only. Hitting the mainstream countdown had taken a while: Taylor’s first solo single had been issued in April 1961.

Quoted in an early music press article on his band Chapterhouse, singer-guitarist Stephen Patman said their ambition was “to have our records on sale in 20 years’ time. To leave something behind when we die." That was September 1990, in a piece tied-in to their soon-to-be-issued debut single.

“Soul Scene,” by Echoes Limited, is built from elements of the James Brown sound. But it’s put together in such a way that the result is unfamiliar. The angular drum groove edges towards a 5/8 shuffle. The circularity of the guitar suggests Congolese rumba. Funk, but outside recognised templates.

Then there’s “Anoshereketa” by Oliver & The Black Spirits. The swirling township structure is recognisable but the drums and the nature of the guitar playing – clipped and spindly, respectively – give an edge. This music is hard to place aesthetically and geographically.

Sixes and Sevens is a surprise. A big one. Since leaving Siouxsie and the Banshees in September 1979, John McKay has largely been a mystery. On record, the only suggestion this influential guitarist had continued with music was the EP his post-Banshees band Zor Gabor issued in 1987. Otherwise – nothing.

The blurb on the front of the double-CD set The Hamburg Repertoire says it collects “The original recordings of songs performed by The Beatles on stage in Hamburg.” Disc One opens with Little Richard’s “Long Tall Sally.” Disc Two ends with Chet Atkins’ version of the “Theme From ‘The Third Man’.”

It would have been hard to pick up a copy of the album credited to and titled 1001 Est Crémazie in 1975. Just 500 copies were pressed. It didn’t reach shops but was circulated amongst the musicians playing on it, their friends, families and fellow students at Montréal’s Collège André-Grasset, the school at which those on the album were pupils.

In October 1967, John Lee Hooker released a single titled “The Motor City is Burning.” The song commented on the civil unrest which had taken place in his Michigan home city of Detroit that July. “Oh, the motor city's burnin',” sang Hooker. “My home town burnin' down to the ground, Worser than Vietnam, Well, it started on 12th and Clairmont, this mornin'.”

Stereo Instrumental Music was recorded in July 1976 and originally issued only on cassette. The release was organised by what was credited as the “Sun Shine Music Shop,” an enterprise which seems to have left no additional imprint. No further “Sun Shine Music Shop” albums are known.

The sticker on the front cover says “The heaviest proto-metal compilation ever released.” And considering the label behind Yeah Man, It's Bloody Heavy is Rise Above, founded by former Napalm Death and Cathedral frontman Lee Dorrian, this is not idle hubris.
