Anthony Platt, known professionally as Unk, was an American rapper, DJ, and hype man who became a defining voice in the mid-2000s snap music scene, best known for his infectious and massively popular single "Walk It Out." Born in Atlanta, Georgia, Unk emerged from the city's vibrant hip-hop culture, initially building a reputation as a skilled DJ and hype man for other artists before stepping into the spotlight with his own music. His stage name, a playful abbreviation of "unknown," reflected his early behind-the-scenes status before his breakout.

Unk's career ascended rapidly with the 2006 release of "Walk It Out," a track that perfectly captured the energetic, dance-oriented sound of Southern snap music. The single, driven by its minimalist beat and Unk's charismatic, instructional-style lyrics, became a cultural phenomenon. It peaked at number two on the Billboard Hot R&B/Hip-Hop Songs chart and crossed over to the Billboard Hot 100, achieving widespread popularity. The song's signature dance moves were further popularized when producer DJ Toomp created an official remix featuring a verse from André 3000, which appeared on the soundtrack for the film ATL. This remix significantly amplified the song's reach and cemented its status as a club and radio staple.

Capitalizing on the success of "Walk It Out," Unk released his debut studio album, "Beat'n Down Yo Block!," in 2006. The album featured production from prominent Southern beatmakers and included other regional hits like "2 Step" and "Show Out." His music was characterized by its party-ready atmosphere and straightforward, catchy hooks, making him a favorite in the dance-centric subgenre of hip-hop. While subsequent releases did not achieve the same monumental commercial success as his signature hit, Unk remained a respected figure in the Atlanta music scene, continuing to perform and release music that celebrated the city's enduring influence on hip-hop and dance culture.

Beyond his own recordings, Unk's impact was felt through the lasting legacy of "Walk It Out." The track has been extensively sampled, referenced, and covered by numerous artists across genres, demonstrating its enduring influence. It became a go-to song for sporting events, parties, and pop culture moments for years after its release. Unk's contribution as a rapper and DJ provided a pivotal soundtrack for a specific moment in hip-hop history, ensuring his place as an architect of a sound that dominated airwaves and clubs in the 2000s.
