Second album Pollution followed the same route of Fetus with a minimalist sound mainly based on the use of a VCS3 synth, unusual lyrics, complex arrangements. Drawing heavily on the VCS3 synthesizer, Battiato and company (besides himself, three backing band members play synth as well) give Pollution an extreme electronic edge. With comparisons to Ash Ra Tempel, Faust, and Pink Floyd, Pollution was declared 'genius' by Frank Zappa. Fetus and Pollution are considered Battiato best records for prog fans.
