Luca Gianquitto is a Naples-born jazz guitarist and composer who trained at the Conservatory of Naples, earning a master's degree in Jazz Music with a specialization in big band arrangement and jazz improvisation. In 2005 he was recognized among the "New Italian Jazz talents" by the Chicco Bettinardi commission, a recurring Italian jazz-talent competition that has also named guitarist Chiara Izzi and pianist Tommaso Perazzo in other years. The same year he signed with the label Wide Sound and released his debut instrumental album, My Big Room. A track from that record, "Floriana," was later included on the compilation Italian Jazz, Vol. 3 (2010), alongside other Italian jazz musicians of the period.

In 2013 Gianquitto founded a guitar school in Amstelveen, in the Netherlands, where he had relocated; by 2017 it had grown to a staff of eight teachers and roughly 150 students, and the school (now operating as LG Guitar Academy) states on its own site that it has since trained over 1,000 guitar students and teachers in total. In 2014 he published a treatise on jazz harmony, "Le scale napoletane nel jazz" ("Neapolitan scales in jazz"), through the Italian jazz education site JazzItalia.net, examining how the melodic and modal vocabulary of Neapolitan song can be applied to jazz improvisation.

Gianquitto released a second instrumental album, Nibiru, in 2016 on his own LG Music imprint, recorded with a quartet of Dutch jazz musicians: pianist Bert van den Brink, bassist Jasper Somsen, and drummer Haye Jellema. The album was presented in a sold-out concert at the Royal Concertgebouw in Amsterdam on September 25, 2016. Over his career he has performed at the Montreal Jazz Festival, the Istanbul Jazz Festival, and Eurojazz in Mexico City, and has recorded guitar parts for film scores, big bands, and rock projects. His own guitar academy's website also credits him with collaborations alongside guitarists Tommy Emmanuel and Joscho Stephan, a claim not independently confirmed by another source.

Gianquitto's only individually documented Discogs credit predates his recognition as a jazz artist: as a teenager or young man, he played guitar on Neapolitan-song singer Mino Germani's 1998 album Antiromantica (Emmegi), a Neapolitan-song (canzone napoletana) record outside the jazz genre. Because Discogs carries neither of his own jazz albums, most of the biographical detail above is drawn from Wikipedia, Wikidata, and his own guitar academy's website rather than the Discogs database; the Discogs-verifiable portion of his catalog is limited to that one 1998 session credit, as detailed in discography-full.md.

Gianquitto describes his own sound as Mediterranean, built primarily from jazz vocabulary but drawing on blues and rock guitar traditions as well, in the tradition of jazz-rooted instrumental guitar composers rather than a straight-ahead combo player. His academic writing on applying Neapolitan song scales to jazz improvisation reflects a career-long interest in bringing the melodic material of his native Naples into a jazz harmonic framework, an interest also visible in his choice of "Floriana" (a reference in the Neapolitan tradition) as the lead single from his debut album. His two-decade gap between studio albums, and the sold-out Concertgebouw premiere of Nibiru alongside established Dutch jazz players Bert van den Brink and Jasper Somsen, reflect a career built more around live performance, session work, and guitar education than a large leader discography.
