Cookin Soul

Cookin Soul is, as far as I have understood, a spanish producer duo.They specialize in makin' rmx's(filled with soulful vocal- and instrument samples). Almost every beat they've made, is worth checkin' out.This is a remix of the classic track, Fakin' Jax by INI.Like the sample on this rmx, plus I've heard it a million times before(the sample). Just can't figure out who the sampled artist is. So if you know who it is, please let me know!!
