Seeking very obscure 70's bands

Released in 1976, Se Allous Kosmous, the brainchild of Greek virtuoso Iraklis Triantfyllidis—who wears many hats as a singer, composer, and multi-instrumentalist—remains a rather obscure gem beyond the devoted Greek fanbase. However, I daresay this album poses a formidable challenge to Aphrodite's Child’s 666 and is deservedly vying for the prestigious title of the Olympian sovereign of Greek progressive rock. Iraklis is listed as a prog-folk act in PA, probably due to incorporating the elements of traditional Greek music in his music, but to illustrate the symphonic grandeur of Se Allous Kosmous, one need only consider its impressive roster: a staggering assembly featuring eighty instruments played by twenty-three musicians, alongside seven lead vocalists, an orchestra, and a choir; it seems that Iraklis Triantfyllidis earned his stripes in the prog world when he enlisted no fewer than five Moog synthesiser players for Se Allous Kosmous.

This album stands alone in the realm of Mediterranean prog. It is emerging as a veritable colossus among albums—a grand double LP that seems almost tailor-made for the extravagant progressive scene of the 1970s.
