Glover directed the music video for the song "The Pressure" by Jhené Aiko, whose previous single, "Bed Peace", had featured a guest appearance by him. On October 2, he released a mixtape titled "STN MTN" and the following day an EP titled "Kauai", which spawned the single "Sober". While "STN MTN" was a free download, the proceeds of "Kauai" went to law enforcement policies, maintenance and preservation of Kauai island. Glover described them as a joint project and the "first concept mixtape ever" that continues the story told in "Camp" and "Because the Internet". At the 57th Annual Grammy Awards, Glover received his first Grammy nominations in Best Rap Album for "Because the Internet" and Best Rap Performance for "3005".
