The music of Italian progressive rock band D.F.A. became increasingly complex in the years following the group's formation. While their early repertoire, composed by drummer/vocalist Alberto DeGrandis, inspired comparisons to British space rock bands, including Gentle Giant and Pink Floyd, their later material was enlivened by polyrhythms, cascading chord progressions, and jazz influences. Formed in Verona, Italy as a trio featuring DeGrandis, bassist Luca Baldassari, and keyboard player Roberto Tommasini, D.F.A. were quickly expanded by the addition of guitarist Silvio Minella. Recording a demo, Trip on Metro, in 1995, D.F.A. caught the attention of Deus Ex Machina vocalist Alberto Piras, who agreed to produce their debut CD, Lavori in Corso.
