Unlike many a box-set retrospective, this 1997 four-CD collection is clearly tailored for Doors aficionados rather than those curious but not overly familiar with the legendary '60s band's career and oeuvre. The first three discs are filled with previously unreleased live tracks and other rarities, such as the band's early demos, which found them slowly building a foundation stemming from each member's clear strengths and influences: Manzarek's classical background, Densmore's jazz, Krieger's rock, and Morrison's blues. Disc 4 features band favorites rather than hits, per se, and thus continues the insider tone taken by the compilation. Once you're inside, though, the rewards are many.
