2009 release, a string quartet tribute to Billie Joe Armstrong and the boys' monumental release. When people talk about the most important Rock albums of the new millennium, Green Day's American Idiot will be at the top of the list. American Idiot showed that Green Day could Rock and still speak their minds. Vitamin String Quartet has reworked this Grammy-winning modern classic, translating the album's epic sweep into powerful arrangements for violins, viola and cello.
