With Roger Drein and ex-Fear of God guitarist Reto “Tschösi” Kühne, Phillips formed the group PK in 1991. PK created a series of privately staged ritualistic performances, usually of an acoustic nature, improvising using different instruments for each session according to pre-determined conceptual frames and settings including playbacks of the previous sessions. The final week of 1992 saw PK locked in a studio, living out of tin cans and recording what was to be a triple album called “Tonkneten” (“kneading clay”). A photo session of the band actually kneading 100 kilograms of clay with the studio recordings playing back was made for the cover. With the group’s demise in 1993, however, plans for an eventual release were abandoned, but two decades later the material still sounds good so an eventual release is an option.
