The "Peanut Vendor" was the first recording of Cuban music to become an international hit. It was described on the label as a "rumba", perhaps because the word "son" would not be understood in English. The label stuck, and a 'rumba craze' developed through the 1930s. This kind of rumba was introduced into dance salons in America and Europe in the 1930s, and was characterized by variable tempo, sometimes nearly twice as fast as the modern ballroom Rumba.
