The countdown is under way for ‘Magnum – A Taste of Reggae Sumfest’, following Thursday’s mid-morning media launch, where organisers confirmed preparations are in full swing for the Gully/Gaza-themed event. Set for July 18 at Plantation Cove in Priory, St Ann, the one-night staging will take place outside its usual Montego Bay home. Dancehall heavyweights Vybz Kartel and Mavado are billed as headliners, joined by Jamal, Ayetian, Queen Ifrica, Harry Toddler, Shawn Storm, Marcy Chin and Young Wild Apache.
