For years and years, Masta Ace was the definition of a slept-on MC. He was the forgotten member of the Juice Crew, a classic New York rapper lost in the shuffle of a million other New York rappers. His legacy would have been largely forgotten if it wasn't for Eminem, who championed the rapper, thanking him in a Grammy speech and claiming that Ace's SlaughtaHouse was one of his favorite albums. Of course, Slim Shady has a gazillion fans who then sought out Ace's catalog, which put Ace on the radar of even the most casual rap fans.
