rapper: doseone (look for him slaughtering eminem in a freestyle battle on youtube. protip: eminem kicked writtens in all his battles)

producer: this is harder... maybe el-p, maybe jel (doseone's counterpart in themselves), maybe kanye... maybe buck 65. maybe mf doom. i dunno. jel is definitely one of the best live producers on the planet, he tears it up on his mpc. YouTube - Jel Drum and Sample Practice 11.18.07
