Friday, Oct. 29 was Kweyol Day, a celebration of island identity and culture. While the official language of the Commonwealth of Dominica is English, 80 percent of the population speak Kweyol, a legacy of early French settlement. Kweyol language and folk culture, after being sidelined, dismissed or denigrated during the British colonial period, has played an important role in forging the identity of independent Dominica since 1978. People's irritation with a late start was quickly dissolved. After the Stars, the Vodou rhythms of Haiti's seminal roots music band Boukman Eksperyans reverberated through Festival City. Named after the Vodou priest who presided over the ceremony that ignited Haiti's slave rebellion, Boukman Eksperyans has been at the forefront of taking the Vodou beat into the arena of world music. Tabou Combo, the most famous and long-lived Haitian Konpa band, seemed reluctant to leave the stage, but from 5 a.m., Festival City was overrun by WCK, [Dominica]'s marathon bouyon band, with whom I was still chipping at breakfast time. Not even a large pot of extra-strong Dominican coffee could revive me, and I retired battered and rambling in Kweyol, to recover in Trinidad.
