Antonio Jasevoli was born in 1963 in Naples. He earned a diploma in classical guitar from the Conservatorio Statale di Benevento in 1989, then continued his studies at summer courses at Berklee College of Music and privately with a striking run of American guitarists: John Scofield, Jim Hall, Joe Diorio, Mick Goodrick and Mike Stern.

In the 1980s, still based in Naples, Jasevoli worked alongside musicians including saxophonist James Senese, drummer Tullio De Piscopo and guitarist Antonio Golino, inside the city's Neapolitan fusion and pop scene. He relocated to Rome in the early 1990s, where, according to his own biography, he spent time in clarinetist Tony Scott's band — a credit not independently matched to a specific dated recording in this build (see notes). What is independently verifiable from that period is a sustained partnership with bassist and cellist Paolo Damiani, already profiled on this site: Jasevoli plays guitar on Damiani's Eso (1994, Splasc(H) Records), a landmark session that also carries trumpeter Paolo Fresu, clarinetist and saxophonist Gianluigi Trovesi, pianist Danilo Rea and drummer Roberto Gatto — all four already profiled on this site — and again on Sconcerto (1999, Il Manifesto), a spoken-word collaboration with writer Stefano Benni built on Damiani's music and double bass. In 1993 Jasevoli also recorded on guitar for the pop-satire group Avanzi Sound Machine's Live (Polydor), arranged in part by Danilo Rea.

Jasevoli's catalogue as a leader began to take shape from the mid-1990s: Astralia (1995, Modern Times), a duo record with Aldo Galasso that Discogs tags "Jazz-Rock," and Triotherapy (1997, Cafèvoltaire), on electric guitar alongside Roberto Gatto (drums), keyboardist Paolo Emilio Marrocco and reedist Marco Conti. In 1996 he served as solo guitarist for the Balletto di Toscana dance company's production of La Tempesta.

Since 2007, Jasevoli has combined performing with teaching. That year he was appointed to teach Jazz Guitar and Harmony, Analysis and Improvisation Technique at Rome's Conservatorio Santa Cecilia — the first jazz guitar instructor in the conservatory's history — a position he still holds; he has also taught at the conservatories of L'Aquila ("A. Casella"), Latina ("O. Respighi"), Frosinone ("L. Refice") and Florence ("L. Cherubini"). The same year he appeared as solo guitarist with the Parco della Musica Jazz Orchestra under the direction of American composer Maria Schneider, and released Tie under the billing Antonio Jasevoli "Tie Trio."

The 2010s opened a run of releases on Rome's Parco della Musica Records and elsewhere. Raj Trio (2010) paired him with tenor saxophonist Marcello Allulli and drummer/percussionist Michele Rabbia. My Own Experience: The Music of Jimi Hendrix (2012, Zone di Musica), billed to the Tie Trio "with Antonello Salis," reworked Hendrix's songbook for a chamber-sized jazz group with the accordionist, already profiled on this site. The same year, Quiet Journey (2012, Parco della Musica Records) reunited Jasevoli with Paolo Damiani and Gianluigi Trovesi, alongside percussionist Fulvio Maras, under the name Antonio Jasevoli Chamber Project — an acoustic, ethno-classical-leaning set built around classical guitar. In 2013, Tetris (Parco della Musica Records) paired him with trumpeter Fabrizio Bosso, already profiled on this site, British saxophonist Andy Sheppard, pianist Enrico Zanisi and drummer Emanuele Smimmo, alternating acoustic and electric guitar textures across a set reviewed by All About Jazz. In 2014 he guested on trumpeter Luca Aquino's Rock 4.0, already profiled on this site, the covermount disc for Musica Jazz magazine's July issue, and is also credited on Aquino's later track "OverDOORS," released on the Parco della Musica-affiliated Tǔk Music imprint.

Jasevoli directs La GEO — the Guitar Experience Orchestra, an ensemble of roughly 30 guitars drawn from Santa Cecilia's student body — as its arranger and composer. Since around 2015 he has also pursued The Wolf Session, a duo of extended improvisation with drummer Mauro Smith ("El Guitar" and "Virtual Drums," in the project's own billing), released in 2017 via the Videoradio label; this release is not indexed on Discogs and is recorded here as press-sourced (see notes). In 2020 he appeared as a guest on trumpeter Angelo Olivieri's Other Colors (Aut Records), already profiled on this site, playing guitar and effects alongside electric bassist Lorenzo Feliciati and American drummer Bruce Ditmas. Jasevoli's own promotional biography also credits collaborations with Kenny Wheeler, Steve Grossman and Bob Brookmeyer; none of these are matched to a specific Discogs-indexed recording in this build and are recorded here as named but not independently verified (see notes).

Jasevoli's guitar work spans a wider stylistic range than most subjects on this site: Discogs' own genre and style tags across his catalogue cluster on "Jazz," "Jazz-Rock" and "Contemporary Jazz," and his own biography describes a personal synthesis "from rock to jazz, to ethnic music, from electronics to classical guitar, from European composition to contemporary improvisation." He is frequently credited, including in his own official biography, as an early and influential user of electronic effects on the electric guitar within Italian jazz, a thread audible on the alternating acoustic and electric writing of Tetris. At the acoustic end of his output, Quiet Journey leans on classical and nylon-string guitar technique inside a small chamber ensemble, with press coverage describing its ethno-classical, ritual-inflected character. His longest-running acoustic-jazz alliance is with Paolo Damiani, spanning Eso (1994) through Sconcerto (1999) to Quiet Journey (2012) — a partnership of nearly two decades. As an educator, he built the first dedicated jazz guitar pedagogy at Rome's Santa Cecilia Conservatory and extended it into an ensemble format with La GEO, arranging for a guitar orchestra rather than a conventional combo.
