The Jolly Boys are old men from Port Antonio, Jamaica, playing modern mento music, one of Jamaica's original musics. They made some awesome covers of international hits, like 'Rehab' or 'Riders on the storm'.
"The well-seasoned and ever energetic Jolly Boys thrash out this new mento sound with as much heart and flex as any contemporary performer. Lead singer Albert Minott’s saturated vocals, natural retro chic stylings and limitless charisma convey an uncommon originality and musical creativity that is entirely his own." (from the official website)
I think the way they perform these songs is much better, than any other.
