On November 9, 2007 appears as “Grün & Blau” (Green & Blue) a retrospective of East Berlin punk band legend Feeling B, in which Rammsteins Flake Lorenz and Paul Landers collected their first experience as musicians. “Grün & Blau” is not primarily retrospective, but also the publication of numerous hitherto missing songs. Flake has spent the last year in his old recording archive to sift, select songs and to mix them, with the aim to give the songs new sound, which was wanted already when they were young! “Grün & Blau” is accompanied by a 120-page hardcover book in which Flake published a selection of original texts, which are now seen from the modern point of view.
