For Finnish composer Osmo Lindeman, the decision to pursue electronic music was made in 1968 during a visit to Poland. He had recently started using graphical notation for the scores of his compositions and was having problems getting conductors and orchestras to follow what he wanted.

The Basel Chamber Orchestra’s 21 string players on tour are an extraordinary set of musicians. Not only did they begin their programme in Manchester with Vaughan Williams’ Fantasia on a Theme by Thomas Tallis, requiring at times one-to-a-part playing to accomplish its multi-voice textures, but eight of them put down their instruments and transformed into a choir for the piece that followed.

Targets (1968), Peter Bogdanovich’s first feature is generally regarded as a great film. And yet, it came out of a mixture of false starts and opportunism. Could it be that its unique quality, the elements which make it stand out in the history of cinema, owed as much as anything else to the randomness that accompanied the movie’s creation?

The Biba dresses are way too colourful, the shop’s interior about 10 times too bright… and did anybody really say ”happening threads” in 1965?

In September 1955, the grandly named London Skiffle Centre set up for business each Thursday in a room above the Round House pub in Soho’s Wardour Street. A prime mover in the venture was blues acolyte Cyril Davies. Two months after the opening, Lonnie Donegan’s “Rock Island Line” was issued as a single. It was previously out as a track on a 1953 Chris Barber album. Despite the wonky timeline, the skiffle boom was on.

Seeking to be both a documentary and a musical tribute to Marc Bolan, AngelHeaded Hipster doesn’t quite pull it off on either count. It’s based around the making of an album (whence the film gets its title) of versions of Bolan’s songs by an interminable list of artists including U2, Joan Jett, Devendra Banhart, Macy Gray, Beth Orton and many more, produced by Hal Willner and released in 2020.

“March of the Flower Children” was a June 1967 B-side by Los Angeles psych-punks The Seeds. The track was extracted from their third album Future, a peculiar dive into psychedelia which was as tense as it was turned on. While the song’s lyrics referenced a “field of flowers,” a “painted castle” and a sky “painted golden yellow” the mood was jittery, unstable.

Between the late 1950s and around 1971, Robert “Mack” McCormick (1930–2015) travelled through his base-state Texas, Alabama, Mississippi, west Louisiana and parts of Arkansas and Oklahoma looking for musicians to record. It wasn’t a random process: he covered 700 counties using a grid system, so nothing would be missed. As well as tapes, he made lists, filled notebooks and took photos. He kept everything.

It’s 15 years since Judy Collins last stepped out at the Cambridge Folk Festival. She was a mere 68 then and, in the time since, little has changed except her hair, the famous rock-star mane lopped so that she now resembles the cover of those classic early Sixties’ albums.

Restraint wasn’t the watchword. Around March 1965, Heinz was in Joe Meek’s North London recording studio taping “Big Fat Spider,” which became the B-side of his April single version of “Don’t Think Twice it’s Alright.” A run-through which didn’t end up on the record found guitarist Richie Blackmore tossing off blistering lead runs so frenzied, so spikey, so wayward they might – had the track been issued – have caused radio producers to check whether the single had a pressing fault.
