Kiss have never been known for doing things the simple way, so it should come as no surprise that their first full career retrospective should arrive jam-packed with enough bells, whistles, and offbeat oddities to have every member of the Kiss Army (active or retired) absolutely salivating. This six-hour collection presents 94 Kiss Klassics -- the rock anthems of several generations of fans since the band's 1974 debut. But the box's real Kalling Kard is its generous sampling of previously unreleased material. Thirty of these gems, selected by the band members themselves, go back as far as 1968 and include solo cuts by Paul Stanley (the no-nonsense boogie "Stop, Look to Listen") and Gene Simmons (the surprisingly breezy pop tune "Leeta"). The set also dips deep into the vaults for material by Wicked Lester (the band that evolved into Kiss) and live songs, including a blistering "Acrobat," which dates to 1973. Besides a bevy of demos for songs like "God of Thunder," "Love Gun," and "Radioactive" (on which Simmons plays all the instruments), there's plenty of material that illustrates the theory of evolution, Kiss-style. To that end, the band chose to include "Bad, Bad Lovin' " (which ultimately became "Calling Dr. Love"), "Mad Dog" (which morphed into "Flaming Youth"), and "Ain't That Peculiar" (the genesis of "Little Caesar"). The set is available in a "standard" box as well as in a lavish guitar-case replica edition worthy of prominent display: All editions contain a photo-packed 120-page book documenting the long, strange trip on which Kiss have taken their fans for more than 25 years.
