Jamaican entertainers need to work on their stage-craft.Veteran producers are urging Dancehall\/Reggae stars to take rehearsals more seriously.According to Patrick Roberts of Shocking Vibes Productions, artiste should realize that they are only as good as their last hit or performance. The veteran producer and event promoter went on to emphasize the importance of rehearsals to every performing artiste."One of the things to entertain is to do proper rehearsal, and it is very sad to hear an artiste run on stage and state, 'Me nuh rehearse enuh' and then expect, if it is there is a supporting band, for the musicians to create magic. Synergy between the band and an artiste enhances the performance," Roberts told The Star.Roberts claims that a good stage performance is paramount to mainstream success and longevity within the business."Any serious manager will take the career of their artistes paramount by doing right by them. It is not about going to the stage show to collect the balance of the agreed fee, but preparing the artiste for every single performance," he argued. "Each performance requires a particular level of preparation too, meaning if you perform in MoBay, it is a different type of audience in Negril; a Reggae Sumfest different from another show. When talking longevity, managers must invest in the artistes' career and every good performance gives a next show."Roberts' claims were also echoed by fellow producer, Dj Frass, who criticized the efforts of many Jamaican acts. According to Frass, they need to let go of their overblown egos and put in the necessary work needed to succeed.He also advised younger talents to learn from their peers, saying "It nah hurt fi watch how a next man perform either, but put in the work so you can do better."
