About Jeroen.

Jeroen Vermazeren (1997) is a bass trombonist, tubaist and sousaphonist based in Amsterdam. He works across jazz, big band, orchestral and electronic live projects.

In 2024, Jeroen graduated from the Conservatorium van Amsterdam. He has performed within renowned ensembles such as the Metropole Orkest, Jazz Orchestra of the Concertgebouw and Paradox Jazz Orchestra. He is also a member of JUNO, Chris Muller Bigband, TINASE, Valvetronic and The Legendary Orchestra.

In 2025, Valvetronic released the album Beyond Our Shores in 2025, that surpassed 2 million streams on Spotify.

In 2026, TINASE released its debut album Never Turning Back featuring Marshall Gilkes as soloist: a record full of trombone power and original compositions. Jeroen is the bandleader of this project.

He also performed with The Legendary Orchestra on Sabaton's stadium tour, travelling from show to show by nightliner. The symphonic metal collective grew out of the Legendary Tour 2025 and combines orchestra, choir and the scale of a large metal production.

In 2026, JUNO played ESNS in Groningen after touring the Netherlands with Popronde ’25 and releasing music with LOE. and Ruben Hein. The group combines live saxophone, tuba, synths, drums and programmed elements; its shows are accompanied by PAUW, a responsive light installation that moves with the music.
