The El Dorados were a prominent American doo-wop group in the mid-1950s, best known for their hit "At My Front Door". Hailing from Chicago, they were characterized by their rhythmic vocal harmonies and were primarily influenced by blues and gospel music. The group, led by the distinctive voice of Pirkle Lee Moses Jr., was instrumental in the development and popularization of the doo-wop genre. Their music is regarded as significant in the transition from rhythm and blues to rock and roll.
