I had opportunity discover how marimba is played in Central America, but influence of african rhythms is not as significative as in Colombia. In Chocó region, the main folkloric style is the currulao (dance and rhythm), where marimba transmits a unique deep swing. So just a post to share some rough recordings, which will probably sound familiar to you as these rhythms are still source of influence in some modern productions today (and still the base of actual folkloric music from the Pacific area).
