The Underachievers aren't ones for excessive vocal refrains. The hip-hop duo's 2013 breakout mixtape Indigoism immediately cuts in with AK the Underachiever's quick, wordy verse set over a sinister bad-trip beat. This no-filler style has become a staple of the psychedelic-influenced Beast Coast acts from East Flatbush like Joey Bada$$ and the Flatbush Zombies. The Underachievers search for something more meaningful amid the gentrification of their neighborhood, AK and Issa Gold's battle with mental illness, and institutional classifications they may not accept. On "Sun Through the Rain," Issa Gold raps over a delicate piano and airy synth, "I don't give a fuck about your new sports car/I don't give a fuck about your new whack bars" before fading into some "third eye shit" on the song "Maxing Out." After their recent appearance on Vice's Indigo Children documentary, the Underachievers released a new, less psychedelic mixtape, It Happened in Flatbush. CAMERON CROWELL
