It's the Beasties' lesser-known cuts that really capture the group's improbable evolution. They traded raging guitar riffs for booming 808 beats on snarling punk-meets-rap bangers like "The New Style.” Ditching their drum machines for samplers, they built cut-and-paste masterpieces from the most unexpected beats and hooks, like a groove swiped from The Eagles on "High Plains Drifter.” They even rediscovered their live-band roots with greasy blasts of throwback '70s funk like “The Maestro.” Later on, the group continued to push the boundaries of hip-hop, tackling social ills with noisy bravado on new-millennium jams like “Say It.”
