After dystopian Eftos [Opp. 01-42] Eftos tracked a sci-fi legacy. 1) Exo [Opp. 43,50] a noisy filigree into nature, for headphones. 2) Trivy [Opp. 44,47] one thousand synthesizers, a facile flow. 3) Syntari [Opp. 45-46] alien arrangements, deep space adagio. 4) Vex [Opp. 48-49] a forlorn world, abstraction and isolation. http://eftos.bandcamp.com
