Roger Marcel Cicero Ciceu (born July 6, 1970 in Berlin) is a German jazz musician and the son of the Romanian pianist Eugen Cicero.

He made his first appearance at the age of eleven supporting German singer Helen Vita. He appeared on television for the first time aged 16, alongside the RIAS-Tanzorchester, then under the direction of Horst Jankowski. Cicero joined the Hohner Conservatory in Trossingen when he was 18, where he received coaching in piano, guitar and singing. Between 1989 and 1992, he appeared alongside the Horst Jankowski Trio, the Eugen Cicero Trio (his father’s group) as well as with the Bundesjugendjazzorchester (German Youth Jazz Orchestra), which was then directed by Peter Herbolzheimer. From 1991 to 1996 he studied jazz singing at the Amsterdam Academy of Arts (Amsterdamse Hogeschool voor de Kunsten) at Hilversum. Since then, he has been a guest singer with the groups Jazzkantine and Soulounge with whom he took part in the Montreux Jazz Festival. In 2003 he founded the Roger Cicero Quartet, as well as continuing to perform with his eleven-piece big band. His style is predominantly that of 1940s and 1950s swing music, combined with German lyrics.

Herbert Grönemeyer (born April 12, 1956) is a German musician and actor, popular in Germany, Austria and Switzerland. He starred as war correspondent Lieutenant Werner in Wolfgang Petersen's movie Das Boot, but later concentrated on his musical career. His fifth album 4630 Bochum (1984) and his 20th album Mensch (Human) (2002) are the best-selling German-language records of all time.^{[citation needed]} He is the most successful artist in Germany with album sales of over 13 million albums.

Grönemeyer often refers to his personal roots as lying in the German town of Bochum where he spent most of his childhood, youth and early adulthood. Still today, the song Bochum, first released in 1984, is one of his signature songs, especially during live performances. Being born in Göttingen and not in Bochum he has his own explanation: "I was only born in Göttingen because my mother often fainted when she was pregnant with me. She did this every time she turned to her left side, and no one believed her. In Göttingen there was a professor, a specialist, and he didn't believe her either, at which point she lay down, fainted, and brought me into the world. This is why I was born in Göttingen."

After completing his education and working for Chemigraphics, an art manufacturer, Maffay worked in clubs, where he distributed his music.

Peter Maffay's career started with the publication of his first single, "Du" (You in German). It was the biggest German hit in 1970 and brought Maffay instant fame. With the album Steppenwolf in 1979, Maffay became a major music star in Germany. The album sold 1.6 million copies, making it the best selling LP at that time. In 1980, the album Revanche (Revenge) broke his previous record, selling 2.1 million copies.

Maffay holds the German record for the most number one ranked singles in the single and album sales charts, including 12 albums. In addition, most of his studio albums reached the top ten. He also holds a German record for most albums to have sold over one million copies, with 14. His latest album,Laut und Leise (Loud and Quiet), became the fourteenth.
