Born in Vad, Romania, to Teodor and Livia Ciceu, an Orthodox priest and professional singer respectively, he began to play the piano at the age of four. Aged six, he performed a Mozart piano concerto with the symphony orchestra of Cluj. Although he graduated from the National Conservatory in Bucharest, he abandoned a career as a conventional concert pianist and established his style between classical and jazz piano, introducing swing harmonies into baroque, classical and romantic compositions, often as spontaneous improvisations.
In 1962, while touring East Berlin, Cicero fled to West Berlin. He spent the next two years in Switzerland, where he joined the "Kindli" orchestra of Joe Schmid. After returning to Germany, Cicero produced more than 70 recordings, some of them with the Berlin and Munich Philharmonic orchestras. He had numerous appearances on German TV and enjoyed much success while touring Japan. In 1976 he was awarded the Deutscher Schallplattenpreis for his interpretations of Franz Schubert.
In 1982, Cicero moved to Switzerland, where he died in Zurich in 1997 from a cerebral apoplexy, aged 57. His younger brother Adrian Cicero is a jazz instrumentalist. His son Roger Cicero (1970–2016) was a renowned jazz singer.
