About Southside (music producer)
Joshua Howard Luellen (born February 2, 1989), known professionally as Southside (also known as Sizzle or Yung Sizzle), is an American record producer, rapper and songwriter. Based in Atlanta, he is recognized in the music industry for his aggressive, trap-infused production work for prominent hip hop artists. After meeting hometown rapper Waka Flocka Flame, Luellen signed with his record label Brick Squad Monopoly—an imprint of Gucci Mane's 1017 Records—as in-house talent in 2010. Luellen and labelmate, fellow producer Lex Luger established the production team 808 Mafia that same year; it was credited on several commercially successful releases throughout the remaining decade. As a lead artist, Luellen signed with Epic Records to release his collaborative album with G Herbo, Swervo (2018), which peaked at number 15 on the Billboard 200. His 2022 single, "Hold That Heat" (with Future featuring Travis Scott) marked his first entry—at number 57—on the Billboard Hot 100. Despite not performing on both, he has released several mixtapes as a recording artist.
