Antonello Vannucchi was born in Lucca, Tuscany, in 1936 and passed away in 2019. He was a pianist, organist and vibraphonist who also composed and arranged, and his recorded career has two distinct halves. One is a run of straight jazz records, from a Tuscan vibraphone group in the late 1950s to piano trios and quartets in the 1990s and 2000s. The other, much larger, is the soundtrack and library-music work he did as a staff musician in Rome, where his Hammond organ was the signature sound of the studio quartet Marc 4.

He started as the vibraphonist of the Quintetto di Lucca, founded in 1957 around the brothers Vito Tommaso on piano and Giovanni Tommaso on bass, with drummer Giampiero Giusti and guitarist Gaetano Mariani. The group drew attention at the 1958 Rome Jazz Festival and recorded for RCA Italiana. Discogs lists an EP issued in September 1959, Lullaby of Birdland / Estate '58, on which he is credited on vibraphone and with arranging and writing one of the tracks, and the 1960 LP I 5 di Lucca, a set of swing and cha-cha arrangements of pop tunes. Italian jazz writing says the group spent several months at the end of 1959 as Chet Baker's backing band. After Mariani left it became the Quartetto di Lucca, and its LP Quartetto (RCA Italiana PML 10361, recorded in Rome in 1962 and dated 1963 on Discogs) is the best document of that lineup: an AllAboutJazz review heard a Modern Jazz Quartet influence with looser arrangements, bop standards such as "A Night in Tunisia" next to modal originals, and a vibraphone sound lighter than Milt Jackson's. In the mid-1960s the same players recorded beat-style singles as I 4 di Lucca.

Vannucchi then settled in Rome and spent many years in the orchestra of the state broadcaster RAI, where he also wrote music for television and film. A biography on the International Archives for the Jazz Organ adds that he worked in groups with Lionel Hampton, Lee Konitz, Toots Thielemans, Freddie Hubbard, Sonny Rollins and Chet Baker among others; those engagements are not itemized there and are not confirmed by the recordings that could be checked. In the 1960s he and three RAI colleagues, bassist Maurizio Majorana, drummer Roberto Podio and guitarist Carlo Pes, formed Marc 4, a name built from the four founders' first names. Conceived as a studio group, it played for the film composers Ennio Morricone, Nino Rota, Armando Trovajoli, Gianni Ferrio, Piero Piccioni, Piero Umiliani and Alessandro Alessandroni. In 1968 it recorded Umiliani's "Mah Nà Mah Nà" for the film Svezia, inferno e paradiso, originally a filler cue, that became an international novelty hit. Discogs credits Vannucchi on electric piano and vibraphone on tracks 7 to 14 of the 1990 Liuto compilation of that score. Marc 4 also made its own records, among them I Solisti di A. Trovajoli, Volume 2 (1969), a run of library albums for Nelson Records from 1970 and Gli anni '20 (1974). The Hammond C3 is what Italian Wikipedia names as the group's defining sound. The group's recordings were later collected in the four-disc The Beat Sound of the Fabulous I Marc 4 (2010), and Vampi Soul issued Thrilling Mortale in 2019.

The jazz sessions ran alongside that work. In May 1969 he played organ on Barney Kessel's Kessel's Kit, recorded over three days at RCA's Studio B in Rome with Carlo Pes on electric guitar, Giovanni Tommaso on bass, Vincenzo Restuccia on drums and Ciro Cicco on percussion. Discogs credits him on organ on Giovanni Tommaso's La Banda del Cibo Salutare (1970), a large-ensemble jazz-rock record that also carries Gato Barbieri and Steve Lacy; on Gino Marinacci's .....Idea (1971), where he plays piano and organ and arranged two tracks; on 10 Situazioni (1973), a television-score album by the Dino Piana and Oscar Valdambrini sextet; and on the Jonefle Group's Sappho (1979), on electric piano.

From the 1980s he returned to piano and vibraphone in small-group jazz. The trio album Coliseum Jazz Trio (Edipan, 1985) reunited him with Carlo Pes and added the bassist Massimo Moriconi. He played piano on Sergio Coppotelli's Everithings Music (1986), with the tenor saxophonist Maurizio Giammarco, and on the Alberto Corvini big band's Fireworks (1987). He is the pianist on the self-titled 1991 album of the bassist Giorgio Rosciglione's quartet, where Discogs credits five compositions to his alias Nuan, and he became a regular partner of Rosciglione and the drummer Gegè Munari: on the Irio De Paula Trio's Sem Batera (Philology, 1999), on Mario Schiano's My Funny Valentine (1999), on the Massimo Urbani Quintet's Wild Genius, taken from a live set at the Eddie Lang Jazz Festival in Monte Roduni on August 9, 1992 and issued by Philology in 2005, and on Nicola Mingo's Swinging (2014). He also accompanied the singer Nicola Arigliano from the 1984 album Amorevole to Colpevole (2005), on which he plays piano on all 21 tracks, and Italian Wikipedia says he backed Arigliano at the 2005 Sanremo Festival.

Under his own name he made My Turn (Nelson Records, 2007), with the American singer Beverly Lewis. Discogs credits him on piano, vibraphone and electric organ on every track, with Rosciglione and Munari on most of them, Silvano Chimenti on guitar, Aldo Bassi, Massimo D'Avola and Mario Corvini on horns, and a reunion with Majorana and Podio on track 10. Back in Time (Deneb, 2013), with Majorana and the composer Stefano Torossi, is a set of sixteen short retro and easy-listening pieces in the library-music tradition. He is co-billed on Max D'Avola's Micca's Dream, where he composed two tracks. Further library-music albums credited to him appeared on Deneb, RedGlobe and other labels between 2015 and 2017.

Vannucchi's recorded work changes character with the instrument. On vibraphone, in the Lucca quartets, he played in the Modern Jazz Quartet manner, and the AllAboutJazz reviewer of Quartetto found his sound lighter than Milt Jackson's. On the Hammond he was a groove player: Italian Wikipedia names his organ as the main feature of the Marc 4 sound, and Discogs files that group's 1960s and 70s records under jazz-funk, psychedelic, beat and bossa nova, while it files Kessel's Kit under soul-jazz, the American organ idiom. At the piano he was the accompanist that singers and bandleaders called back: four albums with Nicola Arigliano, My Turn with Beverly Lewis and a series of dates with Giorgio Rosciglione and Gegè Munari, whose Discogs styles run from bop and swing to cool jazz and Latin jazz. He was also an arranger, credited for two tracks of Gino Marinacci's .....Idea and for the arrangement of a Quintetto di Lucca track in 1959.

The honest weighing is that most of his catalogue is soundtrack and library music, written to fit film scenes and television, and that his straight jazz is the smaller part: the Lucca records, a handful of sideman dates and his own My Turn. It is a real jazz career all the same, and the sessions with Kessel and Urbani show that visiting and local bandleaders wanted him at the keyboard. His influences are not documented in interviews or liner notes that could be checked.
