Andrea Glockner (2001) is an Italo-French trombonist, tubist, and flutist, born in Bordeaux into a family where music was always present—his Italian grandfather was a classical tuba player. Andrea developed a passion for jazz after discovering Miles Davis and Louis Armstrong. He began studying trumpet and flugelhorn in Talence and Le Bouscat, under the guidance of Sébastien Brebbia, Sébastien “Iep” Arruti, and Jean-Pascal Cavard. He then joined both the classical and jazz departments of the Bordeaux Conservatory, studying with Jean-Pierre Duffau and Mathieu Tarot. A decisive moment came with his discovery of Bob Brookmeyer and the valve trombone, which he instantly fell in love with. This led him to focus on low brass in jazz—valve and slide trombone, bass trumpet, euphonium, and more. Andrea chose to continue his studies in Italy at the Accademia Nazionale Italiana del Jazz in Siena, studying with Roberto Rossi, Filippo Vignato, Federico Pierantoni, and Joseph Bowie. In 2022, he represented Siena Jazz in an exchange program with the Amsterdam Conservatory. He currently lives in Amsterdam.

Comfortable performing in jazz clubs as a solo guest, Andrea also has extensive experience playing in larger ensembles and big bands, starting in Bordeaux and continuing in Siena and Amsterdam. He has played in big bands led by Sébastien “Iep” Arruti and Mauro L. Porro, as well as in the ONJGT led by Paolo Damiani. He is a permanent member of the JOTC Open Orchestra in Arezzo, with whom he recorded a 2023 album paying tribute to the music of Joe Henderson. He is also a regular member of the Tooscanians, an octet dedicated to the swing music of the big band golden era. Since 2023, Andrea has been part of Silvia Bolognesi’s large ensemble performing a tribute to Gil Scott-Heron, featuring guest vocalist Eric Mingus. Andrea has shared the stage with renowned international musicians such as Enrico Rava, Giovanni Falzone, Silvia Bolognesi, Paolo Damiani, Eric Mingus, Mauro L. Porro, Maurizio Giammarco, Nico Gori, Giovanni Benvenuti, Francesco Fratini, Angelo Lazzeri, Ferruccio Spinetti, Mario Raja, Daniele Malvisi, Cosimo Boni, Francesco Pierotti, Camilla Battaglia, Evita Polidoro, Giovanni Paolo Liguori, Alexis Valet, Thibaud Bonté, Oliver Gatto, Thomas Bercy and many others.

In 2023 he founded the quartet “Across the Lines“, born out of an encounter at the Italian National Jazz Academy. Their debut album, recorded in Siena in June 2024, was released on the Dodicilune label in March 2025. The quartet brings together Andrea with Italo-Dominican pianist and keyboardist Santiago Fernandez, known for his great generosity and sensitivity; double bassist and electric bassist Silvia Bolognesi, a leading figure in free improvisation in Italy and member of the Art Ensemble of Chicago; and Italo-Swiss drummer Alessandro Alarcon, active both on the Swiss jazz scene and in contemporary music. The group has already performed on major stages in Bordeaux, Agen, and Toulouse, twice at the 38Riv Jazz Club in Paris, at the Venice Jazz Festival at La Fenice, Jazz & Wine in Arezzo, Sghetto Jazz Club in Bologna, the Pisa International Jazz Festival, at the Roccella Ionica Festival (Rumori Mediterranei), at the Rocher de Palmer in Bordeaux-Cenon, at Bourgoin-Jallieu and Limoges.

Andrea’s musical language incorporates all elements and currents of jazz, the roots of the blues, and the tradition of the elders, while also exploring a modern direction through free improvisation, and the energy of rock and funk. He is particularly influenced by the teachings of Joseph Bowie, who emphasizes the importance of groove and reminds us that jazz is also dance music. Melody plays a central role in Andrea’s compositions and improvisations. His artistic vision includes the development and promotion of unconventional low brass instruments in jazz—beyond the slide trombone, which remains the only widely recognized solo voice in that family. He believes instruments like the valve trombone, bass trumpet, and euphonium offer unique and valuable contributions in terms of tone, articulation, and ensemble sound.

Andrea is constantly searching for new sensations and sounds to express himself differently. He is currently pursuing artistic research on the flute—an unusual instrument for a jazz brass player—expanding his expressive palette. He incorporates the flute, for example, in performances with Silvia Bolognesi’s ensemble in tribute to Gil Scott-Heron.
