You'll have Boat Bar and Drifters for afternoon and early evening music. Mainly roots reggae but sometimes some blues or other genres. Blue Skies is a very nice place at night and I personally think Woodstock is too. Both have much less of the hustle element going on and both will be playing mainly roots reggae although some other genres occasionally. Roots Bamboo and Bourbon Beach are still the two late night beach bars with music with the reggae cover band type lineups. I assume Alfreds still has live music some nights but I have not been there in a couple of years now so I'm not sure. Nights that each bar has live music rotates and there is a list floating around somewhere if you Google it. For the most part the non all inclusive part of Negril has really become an older crowd with mostly Boomers and then some Gen X people like myself mixed in. There aren't many young tourists that I see at the bars as the ones I do see are mainly down in the all inclusive resorts. So you won't find a whole lot of dancehall unless it's a local themed party night in the tourist beach road area. The only club on the beach I hear much dancehall is Jungle and DJ nights at Bourbon Beach. There are some clubs downtown and in the West End that have it. Mainly a local crowd. 1Fusion Negril located directly in between Travellers Beach Resort and Negril Beach Club Condos is open 24 hours and has karaoke if you're into that or they'll play whatever music you'd like. Kitchen is open 24 hours too. Enjoy your trip.
