Nirvana changed the course of popular music forever and remains an inspiration to those who have followed. The band's musical legacy was illuminated further in November 2004 by the release of the 3-CD/1-DVD box set With the Lights Out, the definitive collection of rarities and outtakes. Now the 22-song, single-disc Sliver: The Best of the Box offers fans audio highlights from With the Lights Out with the bonus inclusion of three unreleased tracks: "Spank Thru," "Sappy," and a rehearsal recording of "Come as You Are."
