This Memphis-based hip-hop crew became one of the genre's most influential collectives in the '90s and '00s, transforming the sound of generations of hip-hop stars. A dark, gothic adrenaline surge, "Tear da Club Up '97" would provide a template for the crunk sounds of those who followed. Project Pat's whimsical "Chickenhead", meanwhile, offers punchy, catchy flows, valuing brutal economy and a winking sense of humour. The group's artistic apex, "Stay Fly", pushes the musical envelope, wrapping their double-time hi-hats and thunderous 808s in lush string samples from classic soul music.
