SEBASTIÁN GRESCHUK

Sebastián Greschuk is a Basel-based trumpet player, composer, and educator known for his innovative approach to jazz and contemporary music, blending improvisation with South American folkloric elements.

Buenos Aires. In Argentina, he received an Honorable Mention from the Fondo Nacional de las Artes and was recognized as “Revelation Musician” by El Intruso following the release of his debut album Paisaje (Ears & Eyes Records, 2019).

Teaching has been a central part of his career. He has worked privately and at institutions
such as the Escuela de Música Contemporánea (Berklee International Network), St.
Andrew’s Scots School, and the Orquesta Juvenil del Sur for underprivileged children. His
pedagogical approach combines composition, improvisation, and ear training, developing
tailored exercises and interactive tools that encourage creativity and independent learning.

In 2020, Sebastián joined the prestigious Focusyear program at Jazzcampus Basel,
performing with artists including Kurt Rosenwinkel, Ingrid Jensen, and Miguel Zenón. He
later completed master’s degrees in composition (2023) and music pedagogy (2025) at
Jazzcampus, studying with Brad Mehldau, Guillermo Klein, and Ambrose Akinmusire.
