Leopoldo Dante Tévez (born March 22, 1942), known as Leo Dan, is an Argentine composer and singer born in Atamisqui, Santiago del Estero Province. He recorded more than 20 albums during his long career during the late 20th century between Argentina and Mexico. His appreciation for Mexican music led him to record with mariachis, and from there he went to international fame. His music was well received by the Mexican public since his voice was a good match to the traditional mariachi sound.
