Shortly after their debut album Weiß Der Teufel, the German group Rufus Zuphall from Aachen released their second and for over 20 years their last album in late 1971. With second guitarist Thomas Kittel, who was also a master of the Clavinet, and Manfred Spangenberg as the new bassist, the band, thanks to an expanded range of instruments, now played a style of rock more firmly rooted in progressive rock, harder in the loud passages and more lyrical in the quieter ones. The eight varied tracks were much shorter (maximum six minutes), more tightly structured and appear significantly more compact in terms of composition. Phallobst is a versatile album, played with virtuosity and featuring a blend of hard rock, folk and blues rock, all with high production quality. Instrumental tracks with German titles alternate with songs sung in English.

Together with the renowned producer Dieter Dierks, the quintet recorded their second LP in July and August of the same year in just a few days at his studio in Stommeln, albeit with many problems. Disagreements with the management and the record company about musical details and versions, as well as personal differences, made further collaboration difficult. As a result, the record company provided zero promotion for the album. In the summer of 1972, the band split up. Released on the legendary BASF sub-label Pilz with a self-deprecating cover illustration, it is now a coveted collector’s item.
