David Santan’s second EP is one of 2017’s most accomplished releases. An inventive, impassioned collection, it anoints the south Londoner as UK rap’s next superstar. “Question Time” is the incendiary centerpiece: a state-of-the-nation polemic vocalizing political and societal concerns with level-headed intelligence. The mood might be somber, but the quality across these seven tracks is so high that Game Over feels entirely celebratory.
