When Juan Luis Guerra recorded LPs like Bachata Rosa, he was standing on the shoulders of Latin-music giants. Specifically, greats like Marino Perez, who popularised bachata in the mid-‘80s with the pained moans and staccato guitars of heartbreakers like “Ay Mami”. Meanwhile, Guerra's vibrant merengue party-starters wouldn't be possible if not for the energetic horns and percussion of Toño Rosario classics like “Vengo Acabando”.
