Even though nothing on Tape Archive Essence 1973–1978 was released at the time it was recorded, every track evokes material which was issued. Any fan of the German legends Cluster and Harmonia needs this album gathering extracts from tapes key member Hans-Joachim Roedelius recorded on his own during the period when both outfits were active.

How Mitch Ryder is seen depends on particular perspectives. The Detroit blue-eyed soul belter racked up a string of US hits on 45 in 1966 and 1967. He made many albums, became an oldies radio staple and a perennial live draw. In the UK though he was small beer and his only sniff at the charts was with “Jenny Take A Ride”, which brushed the outside edge of the Top 30 in early 1966.

 “An exercise in bizarre mixtures, combining the bleak acid hangover of half-hearted Velvet Underground impersonators with muted razzmatazz: a long and rather stylish joke.”

A raga-rock circularity. Finger cymbals. A distant, etiolated female vocal. A fuggy atmosphere. A kinship with Jefferson Airplane’s “Come Up The Years”, The Jesus and Mary Chain’s “Just Like Honey” and The Velvet Underground’s “All Tomorrow’s Parties”. Hangman’s Beautiful Daughters' “Love is Blue” is a beautiful, haunting recording.

“My favorite in the place was Karen Dalton. She was a tall white blues singer and guitar player, funky, lanky and sultry. Karen had a voice like Billie Holiday’s and played the guitar like Jimmy Reed and went all the way with it. I sang with her a couple of times.”

Two of the 84 tracks on A Slight Disturbance In My Mind: The British Proto-Psychedelic Sounds of 1966 are covers of songs from Revolver. One is a rendering of “Tax Man” (sic) by a band named Loose Ends which was enterprisingly issued as a single on the same August 1966 day The Beatles’ album was released.

Two years before he took on The Beatles, George Martin was working with another artiste who would go on to have success in America. Martin first encountered Matt Monro in 1960 when he signed him to the label he ran, Parlophone. The “Portrait of my Love” single charted later in the year. In summer 1961, “My Kind of Girl” hit America’s single’s charts. His 1965 version of ”Yesterday” had a Martin arrangement.

Through previous archive releases or bootlegs, deep-digging Cream fans will already be familiar with much of what’s on Goodbye Tour – Live 1968. The legitimate 1969 album Goodbye Cream included three tracks from the 19 October 1968 Los Angeles Forum show, heard here in full.

The titles conveyed the enthusiasm. “A Girl Named Sandoz”, “Gratefully Dead”, “Monterey”, “San Franciscan Nights” and “Yes, I am Experienced”. LSD, The Grateful Dead, Monterey Pop Festival, San Francisco and Jimi Hendrix. There they were, explicit tags confirming that The Animals’ Eric Burdon had been psychedelicised. Three years on from 1964's “House of the Rising Sun”, he was a changed man.

For record buyers, Bona Rays left limited evidence for their existence. One single was issued by the aptly named Mystery Records in 1981. Pressed in a limited quantity by the independent facility Lyntone, it featured “We're Never Going to Miss You”, a poppy new wave outing with funky bass and stabs of synth, and “Catch 22”, a more up-tempo track which came across as an attractive combination of Pink Military and Teardrop Explodes.
