Of all the people playing fast and loose with house rhythms recently – and there are a lot – Eric Douglas Porter aka Afrikan Sciences is one of the most consistent and interesting, for his ability to fuse extraordinarily sophisticated jazz licks with disquietingly raw – bordering on the industrial – electronic work. Now, he’s teamed up with Ari – a relatively unknown compadre of  Tama Sumo and  Uzuri boss  Lakuti – for some loose and lovely action, including this abstract but irresistible groove.
