From the 1950s to the 1970s, Ethiopian popular musicians included Bizunesh Bekele, Mahmoud Ahmed, Alemayehu Eshete, Hirut Bekele, Ali Birra, Ayalew Mesfin, Kiros Alemayehu, Muluken Melesse and Tilahun Gessesse, while popular folk musicians included Alemu Aga, Kassa Tessema, Ketema Makonnen, Asnaketch Worku, and Mary Armede. Perhaps the most influential musician of the period, however, was Ethio-jazz innovator Mulatu Astatke. Amha Records, Kaifa Records, and Philips-Ethiopia were prominent Ethiopian record labels during this era. Since 1997, Buda Musique's "Éthiopiques" series has compiled many of these singles and albums on compact disc.
