Rabasa was founded in 1998 by the four Ortet brothers. Shortly after, they welcomed several talented musicians into the lineup: singer Terezinha Fernandes, born in São Lourenço dos Órgãos (Santiago); percussionists Hans de Lange from the Netherlands and Mike Shakison from Suriname; and trumpet player Tagus Traore from Guinea Conakry. 

In 2006, percussionist Mike Shakison returned to Suriname, and guitarist Paulo Bouwman joined the band in his place. Following Tagus Traore’s retirement, drummer Nataniël (Tati) Gomes joined in 2022. Paulo left Rabasa in 2022. Tragically, Tati passed away in 2023, after which Hendrik (Diekko) Ribeiro stepped in as a temporary drummer. Shortly after, original member Mike Shakison rejoined Rabasa, replacing Diekko as the drummer.

Over the years, Rabasa’s members have remained deeply connected to Cape Verdean musical roots. Mike and Hans began their musical journeys alongside Américo Brito and collaborated on projects with renowned artists such as Ildo Lobo, Luis Morais, and Manuel d' Novas. Hans has also performed with notable musicians, including Splash, Gil Semedo, Bana, and Djozinha.
