At a time when grunge was certainly in decline, and hard rock/heavy metal acts like Korn, Pantera, etc, were growing in popularity, Candlebox was unfairly neglected by radio, music lovers, and MTV. Despite the hugely successful self titled release two years prior, lucy was discarded by everybody as soon as it was released. And it was their finest work.
Many people complain that Candlebox didn't have a "defined" sound, which was perfectly reflected in lucy. I disagree with those people who see a dramatic shift between the band's first and second albums, but I suppose that is mainly subjective. Lyrically, lucy is simple; Kevin Martin chooses rhyming over substance in many songs, which is fine for the time period when everything was so serious and bleak. I don't see the overall bleakness of lucy like others, although uplifting is not a word one would use for the album or the band itself.
Musically, lucy is defined by the standouts: Simple Lessons, Understanding, and Butterfly (Reprise). Not the radio friendly music the self titled release contained, musically lucy is more "in your face" and raw. Combined with Martin's emotional yet simple lyrics, lucy is a powerful album. Unfortunately the emotion and power was lost on a generation of confused music listeners and has fallen into oblivion. But this is definitely an album worth buying if you're a fan of the first Candlebox album, Our Lady Peace, or Seven Mary Three.
