Managed to succesfully download it not long after my post,
Wow it's good stuff.
Like straight off the first listen;
A Dance (Poland 1977) Great brass.
Mango Boogie (Poland 1977) Love that bass line.
Grupa Organowa - 'alfa centaura' (Poland 1972)
Mahagon - 'pisecne' (Czech 1977)
Gee Whizz (Czech 1978) What is that? A flute? Fabulous.
Do you have any background to this stuff?
