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. During the 1980s, the Derg controlled Ethiopia, and emigration became almost impossible. Musicians during this period included Ethio Stars, Walias Band and Roha Band, though the singer Neway Debebe was most popular. He helped to popularize the use of (wax and gold, a poetic form of double entendre) in music (previously only used in qiné, or poetry) that often enabled singers to criticize the government without upsetting the censors. Contemporary scene The most prominent internationally acclaimed singers are Aster Aweke, Alemayehu Eshete, Gigi, Teddy Afro, Tilahun Gessesse and Mahmoud Ahmed. Tilahun Gessesse was popular through 20th-century and nicknamed "The Voice" due to his prolong tenor vocal. In 2001, Teddy Afro debut his album Abugida and quickly become famous singer in his generation, nicknamed "Blatenaw" (English: The boy). Some commentators also compare Teddy Afro with Tilahun Gessesse by musical style and patriotic sentiments.

Through her 1999 album Hagere and "Abebayehosh", Aster Aweke is renowned for her voice that attracted broader audience. Another noteworthy singer is Neway Debebe, who was very popular among the youth of the 1980s and early 1990s with such songs as "Yetekemt Abeba," "Metekatun Ateye," "Safsaf," and "Gedam" – among others. Abatte Barihun has exemplified all four main on his 2005 album Ras Deshen.

They include Boston's Either/Orchestra,
