Arriving after one previously aborted album and the 2015 death of co-founder A$AP Yams, this is a defiantly upbeat debut. Exemplifying the Mob’s blend of agile lyricism and exquisite production, “Yamborghini High” celebrates Yams with haunted synths and quicksilver scratching. In-house superstar A$AP Rocky is the lyrical MVP but Tyler, the Creator delivers a scene-stealing cameo (“Telephone Calls”) while A$AP Nast’s steely, string-driven “Nasty’s World” is as good as anything bearing A$AP branding.
