Aco Records or ACO Records was a British record label active from 1922 through 1927. Aco was a budget label, producing 10 inch and 12 inch double sided gramophone record. Aco was a subsidiary of the Aeolian Company Ltd. of London, which in turn was an affiliate of the United States based Aeolian Records. The material was mostly popular dance tunes and songs of the day, together with some light Classics selections. Aco seems to have made no recordings themselves, instead taking masters from both British and US Aeolian, as well as leasing masters from US Gennett Records; sometimes these re-releases on Aco had the recording artists listed on the label under various pseudonymns.
