Joji's first EP, In Tongues, was initially released on November 3rd 2017. The EP includes six original tracks, all written by Joji with the exception of "Will He", which West1ne co-produced. It was released on the 88Rising label, and distributed on all major streaming and download platforms by Empire Distribution.
On January 24th 2018, along with the release of the "Window" music video, a deluxe edition of the EP was announced, which was to include two previously released singles ("Plastic Taste" and "I Don't Wanna Waste my Time") as bonus material, along with 8 remixes of the tracks. It was released on February 14th, again under 88Rising and Empire Distribution.
Also on February 14th, an official Joji store (blossomsound.com) opened, selling t-shirts and giving the link to an official, limited 12" vinyl edition of the original six tracks. Only 1000 units were pressed, and they sold out within the day.
Two singles have been released from this EP. The track "Worldstar Money (Interlude)" was originally released in 2016, stylised slightly differently under the name "WORLD$TAR MONEY". However, "Will He" served as the main promotional single from the EP, being released on October 17th 2017. The deluxe edition included "Plastic Taste" and "I Don't Wanna Waste my Time", which had also been released as singles previously.
