Jermaine Dupri He first got his foot in the industry door in the late '90s, doing quite a bit of noteworthy production work for the likes of Jermaine Dupri, Foxy Brown, Mase, and Goodie Mob. However, it was West's work for the Roc-A-Fella label at the dawn of the new millennium that took his career to the next level. Alongside fellow fresh talent Just Blaze, West became one of the Roc's go-to producers, consistently delivering hot tracks to album after album. His star turn came on Jay-Z's classic The Blueprint (2001) with album standouts "Takeover" and "Izzo (H.O.V.A.)." Both songs showcased West's signature beatmaking style at the time, which was largely sample-based; in these cases, the former track appropriated snippets of the Doors' "Five to One," while the latter sampled the Jackson 5's "I Want You Back."
