Sociedades En Tetra Brik & Graphices Artis - INTITULADO (T.B.R. inédit,198?)

A pearl I received few days ago, a collaboration tape, though never issued, between Biel Oliver (SETB) and Miguel Angel Julian (GA). Unfortunately, Biel can not remember accurate year of the cassette, but is confident that it's the end of the eighties.
