Few expect or want Pete Rock and Smif-N-Wessun to reinvent themselves. The promise of Monumental is that the Chocolate Boy Wonder and the Originoo Gunn Clappaz will blend their iconic sounds, and at times they succeed marvelously. On "Fire," the duo breathe a tale of D-boys (and corny pop rappers) swayed by the devil while Pete weaves a hallucinatory beat; for "Do It," Pete samples wholesale from Babe Ruth's classic B-Boy break "The Mexican." "Roses" is a bit of a departure from the gun talk, as Tek and Steele pay homage to their native Brooklyn.
