America (regardless of the languages spoken). If you look - especially if you can do searches in French - you will find plenty of material on Martinique and on the other French-speaking/Kreyol-speaking islands.
There are barrel-shaped drums in Afro-Puerto Rican music, too - called bomba(s). (Also the name for the different versions of the rhythm played on them.) There are some terrific videos of bomba drumming and dancing on Youtube - look for folkloric music of Puerto Rico, "Loiza" (name of a town) and the last name "Cepeda."
