album would be released posthumously two years later after his death under the title You Won't See Me on the Harvest Records label and dedicated to his parents. The Köllen album included a Beatles song (the title-track), which he was fond of, and another whose lyrics were written by Triumviurat's drummer, The Story of Life. Musicians present on the album include, among others, Hans-Jürgen Fritz on keyboards, Brigitte Witt on choirs who would later take part in the New Triumvirate band, as well as Helmut's sister, Elke Köllen also on chorus. Matthias Holtmann played drums while Köllen handled guitar, bass and vocals. Köllen also featured as a guest on songs by the group Jail, including a single called Julie in 1976.

It would be the last album to contain prog-rock; the rest of their discography would not be the same style. This was the main reason for the departure of drummer and lyricist Hans Bathelt, dissatisfied with the direction taken by Hans-Jürgen Fritz and pressure from the record company, which pushed the group towards a more commercial pop music sound. The next album released in 1978, À la Carte, had little or nothing to do with the band of previous years, due to the pressures of the record company that wanted more sales from the group. As the last original member, the other musicians on the album being merely contract players, Fritz did not feel able to protest, and
