The April issue of Catalonian music magazine Enderrock includes a terrific article about Creative Commons and comes with a CD entitled Música Lliure, which features 19 CC-licensed songs from acts like Cheb Balowski, Dijous Paella, and Orxata Sound System. The CD’s bonus track, Gilberto Gil’s “Oslodum,” provides a sonic — and ideological — link to the Wired CD project, which Enderrock’s editors credit as their inspiration. You can download all of the music from Música Lliure for free at culturalliure.org.
