An introduction to Henry Cow that nobody asked for.
Henry Cow's core were three Cambridge University students Fred Frith, Tim Hodgkinson and John Greeves who had formed a blues/folk rock band but had developed an interest in complex, free jazz and modern classical music. Drummer and working class autodidact Chris Cutler joined later and became the band's ideological spokesman. And yes this band is full of ideology, both political and artistic.
Whereas most prog rock starts with references to Sergeant Pepper and Days of Future Past, this is absolutely not the case with Henry Cow who were more inspired by The Soft Machine and the improvised noise of AMM. Their music was both very improvisational and over considered as they would thrash out their ideas in intense band meetings. On first listening it would be difficult to describe their music as rock of any form, rather a distinctly European form of jazz.
The track
Amygdala is one of their most through composed pieces and is a sequence of stitched together spidery passages. It's not heavily rhythmic music, it's not interested in grooves and what little grooves there are are broken up as the tune jumps to new rhythmic patterns which are more likely to be held by the reeds than the bass and/or drums. So the drums and bass are more about providing harmonic and textural substance than a rhythmic lead. Jazz guitar/sax/flute and a very buzzy (Farfisa?) organ map out the tune which despite its highly fragmented nature is actually highly melodic and, I think, full of a very distinctive character. The odd blasts of fuzz bass sound very Soft Machine inspired, but otherwise it's very difficult to place it in any particular musical tradition. Progressive rock bands such as Yes and King Crimson were still very much pop/rock outfits with various baroque elaboration and extension. This is something else where pop/rock traditions are only one relatively minor component. To further discombobulate your average prog rock fan, the emphasis on tight precision has been dropped for a more jazzy looseness and noise is now a central component. It sits parallel to the Canterbury scene, the free jazz scene and freak folk outfits such as Comus and Jan Dukes de Grey.

They weren't confident composers and struggled to come up with enough material for their second album, they took a cue from German avant gardists Faust and used the studio to shape their improvisations. The second half of this album is a wonderland of strange disturbing noise and half sung vocals taking them even further from rock normality.

A little later they merged with eccentric pop band Slapp Happy and produced an album of avant pop/rock and another of fiery Marxist epics (plus some obligatory improvised noise).

For a period they lived on the continent and toured. At this time they composed of Frith, Hodgkinson and Cutler, plus bassoonist Lindsay Cooper, bassist Georgie Born and singer Dagmar Krause. Sadly unusual for the time to have half the band as female members. Here they are playing a Phil Oches cover - one of the more accessible things they ever did.

Their last album is instrumental, less improvisational and closer to modern classical than ever before.

I think they created a melodic and harmonic language to carve out a certain European identity, like they were building something new that nevertheless failed to catch on in any serious way. It's perhaps an odd thing to say given how chaotic and difficult their music was, but I think it's highly melodic and expressive. It feels rooted in folk and classical traditions rather than rhythm and blues. I hear it as melancholic but hopeful. It's a musical language that will leave you hungry for more once you have absorbed it.
