Before bachata became about lyrical seduction and sonic sophistication, the beguilingly rugged style belonged to the working class of rural Dominican Republic, as charted on the austere ‘60s-era Bachata Roja. Delivered in amargue fashion (a.k.a. bitter music), the requinto-driven “Ladrona” depicts a shattered heart, as does the dramatically yearnful “Muero Contigo” (Dying with You). On the flip side, the bongo-laden “Yo Pagaré La Cerveza” chronicles a night of excess and debauchery, while the merengue-tinged “Si Me La Dan La Cojo” hunts its prey.
