Here is a review of Human Clay from rollingstone.com . You may or may not agree with it...
"The relationship between the singer and the guitarist is paramount in spirit-chasing bands, as one reaches for mysticism in words and the other taps it with rock's most heroic instrument. Creed, a band still ensconced in bluster, nonetheless have an interesting pair in singer Scott Stapp and guitarist Mark Tremonti. Stapp, the son of a fundamentalist minister, is wrapped up in his rampages; his virile bray recalls those warriors who turn from bad to good in episodes of Hercules. On Human Clay, Creed's second album, Tremonti finds a way to balance Stapp's sullen tone. He plays ever so delicately, just a few modal progressions, above the heavy crunch of Creed's rhythm section. This minimal technique owes a lot to Jerry Cantrell of Alice in Chains. But emulating that very musical metal band isn't a bad choice." -- ANN POWERS
