{$Ben Harper} is a musical preacher of sorts, never one to be shy in speaking his mind about social conformity. If his first two albums -- {^Welcome to the Cruel World} and {^Fight for Your Mind} -- didn't clue you in, {^Diamonds on the Inside} will definitely do so. {^Diamonds on the Inside} marks {$Harper}'s fifth studio effort, and this time he's emotionally in touch with what makes his heart burst. This is a passionate album, no doubt. His signature Weissenborn guitar joins him once more and {$Harper}'s classic groovy {\funk} is heavy; however, {$Harper} adds {\worldbeat} to his musical plank. From the {$Marley-esque} vibe of {&"With My Own Two Hands"} to the African soundscapes of {$Ladysmith Black Mambazo} on {&"Picture of Jesus,"} {$Harper}'s purist presentation is smooth. {&"When It's Good"} gives a little {\country-blues} twang, while {&"Touch from You Lust"} is a sexy haze of writhing riffs. {&"Temporary Remedy"} follows the {\funk} {$Lenny Kravitz}-style, and {$Harper}'s a bit campy. It's a noticeable change from his typically serious stature and a nice shift in personality, too. {^Diamonds on the Inside} is another stunning effort from one of {\rock}'s underground heroes. {$Harper} has consistently worked with what appeals to him musically for nearly a decade, ignoring what fits the mainstream. {^Diamonds on the Inside} is {$Harper}'s sixth chapter of truth, and just one listen to the electric blaze of {&"Everything"} will convince you.
