I'm down one of my periodic rabbit holes.
This time it is that particular style of European jazz rock and fusion music that flourished in the 1970s: lots of bands coming out of various hyper-local regional scenes, influenced by electric Miles and Mahavishnu Orchestra, and often with strong overlap with the more adventurous art rock scenes (like Canterbury, Krautrock, RIO, Zeuhl, Zappa, etc), often lasting for only one album.
I don't think that we have a discussion on this topic (I had assumed that I had started one, but apparently I haven't, or if I have I can't locate it).
The biggest names in the genre seem to be the British ones, particularly Nucleus, Brian Auger, Colosseum, Bruford, Brand X and Soft Machine. But there are hundreds, from largeish bands like the German Embryo, Czech Modry Efekt or French groups like Gong (post-Aellen), Cortex and Magma (pre-MDK), to one-off records by bands like the Algerian/French Rahmann.
It's a fascinating genre. A lot of it does sound really quite similar. But there's a fun heavily electric sound to it that has never really been replicated.
Any recommendations or thoughts welcome. (Obviously, this being the era of the internet, there are bonus points to be had if the band or album recommended is Czech or from the former Yugoslavia.)
