¡Bom! (Martina and Joy duo) is a Brazilian jazz duo that was formed in 2022 by singer Martina Effy Bergonzoni and guitarist Joy Goh in the Netherlands.
They are one of the very active duos in the scene of this music in the Netherlands, performing at diverse venues including festivals, events, bars, theaters such as Tivoli Vredenburg, Paradiso Amsterdam, Sudwerk Festivals (IT), PrinsjesNach, etc.
In this duo, Martina and Joy play various types of Brazilian music, including Bossa Nova, Samba, MPB, Pagode, Forró, Jazz, and original compositions. With their jazz backgrounds, they add a jazz touch to their interpretations of these genres.
What makes this duo stand out is that the feature of this duo besides their beautiful playing is that - they play multiple instruments.
Martina, the singer, is also a classically trained guitar player. Sometimes, she plays the guitar while singing. Martina also plays hand and foot percussions while singing too. In her performance, you will hear the percussions when she starts dancing.
Joy Goh, the guitarist, is also a Pandeiro and Cavaquinho player. The Pandeiro is a traditional handframe drum used in Brazilian music, producing a loud and resonant sound similar to a light drum set. Cavaquinho is a small guitar-string instrument of Brazilian origin. The fact of being multi-instrumentalists: this duo creates a fuller and more complete sound than we normally expected from a duo; it sounds like a trio / quartet! In 2024 Fall, they were also invited by programmers abroad to perform a series of concerts in Italy in FEB 2025, marking their first international tour.
