The Japanese scene of the 70s had plenty of experiments that blended contemporary and traditional instrumentation – but this album-length jam from percussionist Stomu Yamashta may well be one of the most striking from the time! You'll no doubt know Stomu from some of his later records that got more global circulation – but this set was originally only issued in Japan, and mixes some of his progressive leaning with a very free jazz sensibility – served up by a quartet that also features Masahiko Satoh on organ, Takehisa Kosugi on electric violin, and Hideakira Sakurai on electric koto, shamisen, and more percussion! Stomu himself is unbound, and plays with a frenzy we've not heard before – and the mix of the other instrumentation, especially koto and shamisen, creates all these really unusual sounds and tones throughout. The album features one long track, recorded live at Yamaha Hall in Tokyo! (Rock, Out Sound) CD

Not what you might expect when shopping for African music – unique electronic sounds from Cameroon musician Francis Bebey – as heavy on keyboards as other 70s work is on guitar! There's still plenty of acoustic elements in the mix though, too – lots of earthy percussion at the bottom, which links some of these tracks to other styles of the time – even though some of the more unusual tunes here have these great electronic sounds that almost feel like they came from the late 70s German underground! The mix of modes is breathtaking – as if Moebius and Roedelius recorded with musicians from Lagos – shaking off the colder sounds of the Conny Plank side of the spectrum, to come up with a warm new style that's really unique! Titles include "La Condition Masculine", "Sahle", "The Coffee Cola Song", "Super Jingle", "Pygmy Love Song", "Agatha", "Catching Up", and "Divorce Pygmee".

A masterpiece of new music for guitar from the legendary Glenn Branca – a set that both draws on all the minimal experiments on the New York scene of the 70s, and the big wave of underground music at the end of the decade! Branca effortlessly fuses the rock and compositional communities here – working with Lee Ranaldo of Sonic Youth, and artist Ned Sublette – in a fierce set of tunes that blend four guitars, electric bass, and drums – all with an instrumental frenzy that matches some of the best early jams from Sonic Youth. Branca's approach is less freeform, but has very much the same intensity – and titles include "Lesson No 2", "Structure", "The Ascension", and "Spectacular Commodity". LP, Vinyl record album

"Now you can experience transcendental consciousness without spending 10 years in a Tibetan monastery" – or so the liner notes proclaim – a pretty great description of what's bound to happen after making your way through this very trippy album from the early 70s! The set's essentially a set of long electric guitar solos – played by Wilburn Burchette on his self-created "impro guitar" – recorded with lots and lots of echo, and maybe a bit of distortion too – so that the long, cyclic lines ring out beautifully – with every bit of the hypnotic feel you might expect! The whole thing's almost like an electric version of some of John Fahey's longform solo work – and titles include "Dawn Of Awakening", "Regeneration", "Transformation", "Introversion", and "Piercing The Psychic Heart".

The first release of a groundbreaking performance – David Tudor's 1956 recording of "Music Of Changes" – one of John Cage's first experiments of writing based around the I Ching! The work is based heavily on chance – following charts of possibilities put together by Cage, and extrapolated dramatically by Tudor – who was, at the time, one of the few pianists who really understood Cage's impulses – and could bring them to fruition with a performance like this! CD

Modern art, but of the sonic variety – served up here by composer Daniela Casa on a rare sound library album, but with a free-thinking quality that rivals the best of the avant garde at the time! Unlike some more staid, academic record, there's no overarching concept here – no detailed notes that you need to read to "get" the music. Instead, Casa creates these short, dark little passages of sound – sometimes very abstract, occasionally tuneful – with elements that move between free jazz, atonal piano and woodwinds, offbeat strings, and even a bit of Fender Rhodes! The whole thing's a great reminder of just how much genius was bubbling up in Italy during the 70s – so much so that a record like this, which would have been worthy of release by Columbia or Deutsche Grammophon in bigger scenes, was only pressed up in small quantities by the Flipper music label. Titles include "Concetto Informale", "Dimensione Umana", "Prima Maniera", "Ricerca Della Materia", "Visione Surreale", and "Ricerca Cromatica". (Sound Library, Out Sound) LP, Vinyl record album
