As a farewell to a century of musical innovation, Sonic Youth devote a double album to covering legendary avant-garde recordings such as John Cage's "Six," James Tenney's "Having Never Written a Note for Percussion," and Christian Wolff's "Edges." As a further token of gratitude, Sonic Youth had other avant-garde musicians such as William Winant collaborate with them on these covers.
