In 1966, Jose visited Mar del Plata, Argentina, to perform at the Festival de Mar del Plata. There, he so impressed the RCA Victor executives, that they wanted him to stay and record an album for them in Spanish. They were unsure how they wanted to record Feliciano so Jose suggested he record some of the bolero music of his parents where Jose then added his blues and folk influences from his experiences while playing in the Village. The result was two smash hits with the singles "Poquita Fe" ("Little Faith", also titled "Sin Fe", or "Without Faith"), and "Usted". This was the beginning of a series of successful singles, albums and gold records throughout Latin America and Hispanic communities in the United States where Feliciano revolutionized the sound of the bolero. Some of his most beloved interpretations include "La Copa Rota, La Carcel de Sing Sing, Extraños en la Noche" which charted concurrently as the Spanish version of Frank Sinatra's "Strangers in the Night."
