[2] The duo gained critical and commercial fame with the release of their landmark debut album Dead Serious,[2] which highlighted their unusual rapping style (which they nicknamed "sewage").

Dead Serious went platinum and its lead single, "They Want EFX," (which contains samples from James Brown's "Blind Man Can See It" and Malcolm McLaren's "Buffalo Gals") reached the top ten on the U.S.

The track peaked at #36 on the UK Singles Chart in August 1993 and sold over one million copies in the U.S.[3] As their career progressed, Das EFX's once-distinctive and unique lyrical delivery was imitated by several other artists and became more commonplace.

[2] Derailed by the popularity of their own style, the duo slowed down their fast-paced flow, eliminated the iggedy suffix and downplayed their cartoonish content on their second album, Straight Up Sewaside.

In 2007, Krazy Drayz appeared on the East Coast remix of Nas' "Where Are They Now", alongside eleven other old-school rap artists: Dres, Monie Love, Chip Fu, Positive K, EST of Three Times Dope, Father MC, DoItAll of Lords of the Underground, DJ Spinderella, Rob Base, Mike G. of the Jungle Brothers, and Redhead Kingpin.

They reissued How We Do under the alternate title Old School Throwback on Spotify and other streaming services in 2015; both versions of the album featured Sean Paul on a song “The Memories Remain” which deals with the death of Skoob’s father.

From the time of their debut in 1992 to 1993, several elements of their style were adopted by other hip-hop artists, including Lords of the Underground, Fu-Schnickens, Kris Kross, Common and even, to a lesser extent, Public Enemy.
