What he said.probably not exactly what you're looking for, but if you want some "isom" tropical music, find the buena vista social club.
Right on Matis Yahu is pretty awesome :thumbsup:.These may bee way off from what you are looking for, but an older band is the Melodians, which is older reggae, or you could check out Matis Yahu, Ziggy Marley and the Melody Makers, or the Mighty Mighty Bosstones..... Hope these help....
