This was soon followed by "Rage in Eden" (1981), with the band returning to Plank's studio in Cologne for what turned out to be a difficult recording session. Whereas the "Vienna" material had been performed live a great deal prior to a three-week recording process, "Rage in Eden" took over three months. The album featured a long track in three parts on the second side. The album peaked at No. 4 in the UK, while two singles from the album, "The Thin Wall" and "The Voice", both made the UK Top 20, reaching No. 14 and No. 16 respectively.
