Charlie Zaa has recorded close to a dozen CDs (to date) since launching his career as a solo artist. His CD Sentimientos, in which he sings some past hit songs, sold a reported 3 million+ copies throughout Latin America and the United States. His albums Sentimientos and Un Segundo Sentimiento led to him winning the 1998 Artist of the Year award at the Billboard Latin Music Awards. For his fourth album, Zaa returned to the Sonolux studios in Bogotá where he had made his first album Sentimiento, and to his original producer Milton Salcedo, and recorded old romantic standards, boleros and waltzes in an attempt to duplicate the success of Sentimiento. Zaa’s album De Un Solo Sentimiento was nominated for a Latin Grammy Award in 2002. In 2011, Zaa’s album De Bohemia reached the top of the Billboard Latin Albums chart.
