Eugen and Roger Cicero were father and son, but above all they were extraordinary artists. While Eugen rose to fame in the 1960s as a piano virtuoso, performing with star singers such as Ella Fitzgerald and Shirley Bassey, Roger filled huge concert halls years later as one of Germany's most gifted singers. Their life stories are inextricably intertwined and reveal fascinating parallels – genius paired with unparalleled passion, the overcoming of boundaries, the balancing act between commercial success and artistic integrity, and ultimately the tragic end that continues to shake the music world to this day. In the touching documentary CICERO – TWO LIVES, ONE STAGE, Kai Wessel, Katharina Rinderle, and Tina Freitag reveal the unique father-son relationship between two exceptional talents. Close companions and renowned contemporary witnesses shed light on two geniuses who were always drawn back to the stage. Extraordinary concert moments make the painful void left by their early deaths all the more apparent. An emotional tribute to two brilliant personalities full of contradictions, humor, and inspiration—as free and surprising as their music.
