Public Enemy with the one-two combo, from Yo Bum Rush The Show.
One: My Uzi Weighs A Ton
Staaahp! Uh--uh-uh.. uh-get-downnnn uh-uh (..holdit?!)
One ton is probably a conservative estimate, for a track this heavy. Wrecked cars, crushed into blocks, broken cable TV and drum machines, wire and metal poking out. A cut-and-shunt, welded together, rather than mixed. You could poke your hand through the gaps in the chorus, the scratching will probably cut your arm off if you don't stand a safe distance. Whatever samples were used in this, they were loaded onto the back of a semi, then driven off a bridge.
Two: Timebomb
Jimmy Nolan may be the funkiest man not alive, but for Chuck this is as comfortable as... Arnie riding the Harley in T2. Chuck fires his mouth off like a shotgun non stop, reload in a loop, just like Arnie in that chase in the LA Storm Drains. He refuses to take a breath in the whole three minutes. Starts off flat out, and somehow keeps changing it up, like he's climbing an Escher stair case, or operating the gears on Edward Furlong's Dirt Bike.
