Marino Marini (11 May 1924 – 20 March 1997) was an influential Italian musician, born in Seggiano, Tuscany, into a family of musicians. He studied piano, violin, and composition at the Rossini Conservatory in Bologna. After serving in the military, Marini became the artistic director of the Metropolitan music hall in Naples in 1947, where he developed a deep appreciation for Neapolitan music. His exposure to American jazz during a visit to the United States in 1949, where he met jazz greats like Dizzy Gillespie, significantly influenced his musical style.

In 1954, Marini formed the Marino Marini Quartet, which became highly successful with hits like "Guaglione," "Don Ciccio 'o piscatore," and "Maruzzella." The quartet's music was characterized by a blend of traditional Italian and Neapolitan songs with contemporary American jazz influences. Their rendition of "Guaglione" sold over five million copies and was featured in the film "The Talented Mr. Ripley."

Marini's quartet toured extensively, performing in Europe, the United States, the Middle East, and Japan. He was known for rejuvenating the traditional Neapolitan repertoire with a modern twist, incorporating faster tempos and dance rhythms. Marini's music not only captivated audiences worldwide but also contributed to the success of artists like Dalida, who performed many of his compositions. His work remains a testament to his ability to blend cultural influences and innovate within the musical traditions he cherished.
