Gian Piero Reverberi (born 29 July 1939 in Genoa) is an Italian pianist, composer, arranger, conductor, and entrepreneur.
After obtaining Diplomas in piano and composition from the Paganini Conservatory in Genoa, Reverberi worked in a wide range of media, including TV themes, spaghetti Western soundtracks to pop and rock records. He created the Rondò Veneziano ensemble. He also worked with his brother Gianfranco Reverberi on the song "Last Man Standing" (or "Nel cimitero di Tucson") from the soundtrack of Django, Prepare a Coffin (Preparati la bara!), which was sampled in Gnarls Barkley's hit "Crazy".
As a producer, Reverberi worked for New Trolls and Le Orme progressive rock bands, being also listed as one of the official members of the latter for a short stint. In the 1960s-1970s he was also the producer of several albums of singer-songwriters such as Lucio Battisti, Fabrizio De Andrè, Luigi Tenco and Gino Paoli.
In 1979, he founded the Rondò Veneziano chamber orchestra, which he has led ever since, having been the main composer, arranger, and conductor of the group. They play original instruments, incorporating a modern rock-style rhythm section comprising synthesizer, bass guitar and drums.
