Juan Luís Guerra and his 4-40 group (Roger Zayas, Adalgisa Pantaleón and Kike Rizek) had everyone standing up and swaying to merengue on Saturday evening. He filled the Altos de Chavón amphitheater in La Romana to capacity. An estimated 6,000 persons attended the concert. The concert started at 9 pm and ended at 11:22 pm (27 songs – opening with "El Niágara en Bicicleta" and closing with "La Billirubina"). The climax of the evening was the performance of Mariela Mercado and Maridalia Hernández, original members of 4-40 who had abandoned the group to give more time to their families when the group began its world tours. Guerra is the Dominican who has sold most CDs.
