Joseph David Keery (born April 24, 1992), known professionally in music as Djo, is an American actor and musician.

[4][5] Keery studied at The Theatre School at DePaul University in Chicago, graduating in 2014 with a Bachelor of Fine Arts in Acting.

[6] Keery's breakthrough role was as Steve Harrington in the Netflix sci-fi series Stranger Things.

Since beginning Stranger Things, Keery has also acted in a few independent movies, including starring in the 2020 satire film, Spree.

He also played the role of Walter "Keys" McKey,[12] a game developer, in the 2021 action comedy film Free Guy, which went on to become a major box-office hit.

As of 2019, Keery was no longer a touring member of the band, and he later parted ways due to acting commitments.

[23] In a positive review of the album, NME called Keery "a musician of very high calibre who... dabbles in the kind of inventive, warped psychedelia that gently twists your melon and constantly shapeshifts around you," and compared his music to that of Tame Impala and Ariel Pink.

[28] In 2024, the sixth track of the album, "End of Beginning", was released as a single after gaining popularity and becoming viral on social media.
