Brush up on your Bob Marley at the Reggae Party on Coney Island’s boardwalk this Sunday afternoon. Brooklyn-based DJs will be blasting reggae, ska, and rocksteady music all day at a free “sound system” party, which means that speakers will be directly hooked up to generators in order to recreate an authentic dancehall effect. Adventurous audience members are encouraged to dance and even grab the mic for some freestyling, so be sure to get up, stand up, and have fun.
