Eolika—Varam sintezēt visu bez riska 1969

Another latvian group, Eolika (Эолика); it seems Raimonds Pauls has some connection to the band. The song sounds very modern (for that time) and I like it very very much:

They played cool beats in 1969, however their discography starts since 1980:- (and I’ve found none beat tracks anymore.

P.S. Google translates the title as «We can synthesize all the risk-free».
