Before reggaeton was a thing, El General primed dance floors with this genre-defining 1991 EP—his own Panamanian brand of gasolina. Kicks and snares take over from the very first notes of “Son Bow,” and they don’t let up, proving you don’t have to go to Jamaica to gorge on sensuous, unadulterated dancehall rhythms. Two monster singles (“Tu Pun Pun” and “Te Ves Buena”) carry a dembow sound so potent, it’s still being interpreted and recycled by a new generation of artists.
