Americana prog cover tune anyone? If anyone could pull it off it would be the much-beloved Mexican acoustic rock guitar duo Rodrigo y Gabriela. Huge fans of Pink Floyd, "Echoes" is from their latest album entitled Mettavolution (ATO Records), released on April 26th. It takes up one half of their new album, much like the song did when it was originally released on Pink Floyd's Meddle album in 1971. But this is a much different journey, one accented by stunning acoustic guitar work, the duos interplay creating their own mesmerizing and psychedelic acoustic textures. Sit back and enjoy.
