Boss Up

With his feet planted in the Bay Area\'s sonic soil—check the wobbly bass and slapping snare of \"Stop Signs,\" which is full of references to his Richmond stomping grounds—MC and producer Iamsu! reaches for new melodic heights on this mixtape. He channels his inner Drake on the title track, stretching bars into tuneful curlicues alongside the elastic raps of local legend E-40. And his mellow cooing melds perfectly with the pan flute-embellished R&B of \"By My Side\" and synthy quiet storm of \"Shang Hai.\"
