Extremely hard to find early electro-acoustic / concrete music album recorded in Cuba by Carlos Farinas released on Areito in 1980. This Aguas Territoriales / Musica Electroacustica consists in 2 one side long pieces where Farinas crafted a brilliant mix between concrete music and electro-acoustic sounds. Superb nice copy. Record looks unplayed. Fragile thin sleeve is strong VG++ light ringwear.
