Chipmunk soul

Chipmunk soul is a Hip Hop production style pioneered by Just Blaze and Kanye West around the dawn of the 2000s that featured sped-up Soul samples for the hook of the songs. Some early usage of the technique can be heard in songs like Wu-Tang Clan's "For Heavens Sake" and Mos Def's "Ms. Fat Booty" (produced by Ayatollah), however the genre really came to form with Just Blaze and Kanye West working on a select few songs on Jay-Z's The Dynasty and most importantly 2001's The Blueprint. This new sound ushered East Coast Hip Hop into a new era of post-Boom Bap following Bad Boy Records' glossy sound and the more electronic approach of Swizz Beatz for Ruff Ryders.
