For 25 years, the Federation Sound crew has shepherded the culture of Jamaican dancehall, reggae, and roots music in New York City and beyond. This year Kenny Meez, Max Glazer, DJ Danglez, DJ Mace and Alric & Boyd celebrate the milestone anniversary in Coney Island with the help of Sister Nancy, the pioneering first lady of dancehall and singer whose iconic and instantly recognizable hit “Bam Bam” has been sampled countless times, and Tanto Metro & Devonte, the Jamaican dancehall vocal duo whose 1997 smash “Everyone Falls in Love” took them to the top of the Billboard reggae charts—and secured a permanent place in the pantheon of essential dancehall tunes. Additional artists are to be announced.
