Juan ‘Pacho’ Maglio was the first bandoneon player to make recordings, for Columbia records. In 1912 he recorded Armenonville, the name of the first elegant cabaret/restaurant in Buenos Aires. His nickname ‘Pacho’ became synonymous with records: the recording industry was booming at that time and he was such a success that when a person went to the record store they would say: ‘give me a Pacho’ or ‘dame un Pacho’ meaning ‘give me a record’.
