Although Kid Cudi has always played by his own rules, Speedin’ Bullet 2 Heaven offers some of his most genre-blurring music yet, taking inspiration from the confessional ‘90s indie scene. Over the crunchy guitar and primal drumming of "Confused!," Cudi rattles off suicide scenarios next to lines like, “These walls ain’t talking back/Might as well finally paint them black/I’m out of ideas.” "The Nothing"'s lo-fi vibe recalls the rough-and-ready sound of a Nirvana demo. Still, there are lots of reminders of what we’ve always loved about the boundary-pushing artist; including “Adventures,” which opens with acoustic guitar and his melodic flow before adding an old-school drum break and deep-space echo.
