In February 2017, Jidenna's album, The Chief, was released featuring the song, "Helicopters / Beware" which Jhn co-wrote.[7] The following month, Jhn released another original track, "3 Below."[13] In October of that year, he played at two festivals, Rolling Loud and the Voodoo Experience. He also released another new song, "Hermes Freestyle."[14] In February 2018, Jhn released "I Heard You Got Too Litt Last Night."[15][16] In early March, he released the song, "Albino Blue," and announced the official release date (March 30) of his debut album, Collection One.[17]
